Make your own Magic card!

Final Countdown - B
Sorcery
Exile ~ with twenty countdown counters on it.\\ At the beginning of each player's upkeep, if ~ is exiled remove a countdown counter from ~.
When you remove the last countdown counter from ~ while it's exiled, target player loses the game. Then put twenty countdown counters on ~.

Based on a similar card from Yugioh. That card just said 'you win the game twenty turns after you play this card' with no actual way to keep track of how many turns pass, so I had to tweak it for Magic. Originally thought of giving it suspend, but there are cards (Clockspinning, Rift Elemental) which break that mechanic, so I figured exiling it with unique counters worked better. Couldn't make it a permanent that added or removed counters, because it's not supposed to be breakable with proliferate / Vampire Hexmage. Making target player lose, rather than making you win, also makes it more fun in multiplayer.

I see Theros has been having a rough time!

Inspired by the discussion of the Simic mechanic a while back, I ended up coming up with an idea for a Phyrexian mechanic that has nothing to do with poison and is compatible with +1/+1 counter mechanics:

Dissect - As long as this creature is in your graveyard, creatures you control with +1/+1 counters on them have [effect].

Some card ideas:

Phyrexian Test Subject (2G)
Creature - Horror
2/1
Dissect - As long as ~ is in your graveyard, creatures you control with +1/+1 counters on them get +1/+1.

Avian Experiment (3U)
Creature - Bird Horror
1/4
Flying
When ~ enters the battlefield, put a +1/+1 counter on target creature you control.
Dissect - As long as ~ is in your graveyard, creatures you control with +1/+1 counters on them have flying.

Plague Spewer (3BB)
Creature - Horror
4/4
Deathtouch
Dissect - As long as ~ is in your graveyard, creatures you control with +1/+1 counters on them have deathtouch.

Forbidden Seal - 2BB
Enchantment
Sacrifice twenty nontoken permanents: you win the game.

Gold-Dusted Road
Land
~ enters the battlefield tapped.
{2}, {T}: Create a colorless Treasure artifact token with "{T}, Sacrifice this artifact: Add one mana of any color."
{T}, Sacrifice three Treasures: transform ~.

(Transform)

El Dorado, Golden City
Legendary Land
{T}: Create two colorless Treasure artifact tokens with "{T}, Sacrifice this artifact: Add one mana of any color."
At the beginning of your upkeep, you gain 1 life for each Treasure you control. Then, if you control five or more Treasures, draw a card.

Vivisect RB
Instant
Deal 4 damage to target creature you control. You gain the effect of any abilities that are active as long as it's in your graveyard until end of turn. (This will create a second instance of that ability if the creature dies.)
"See? You didn't need that after all!"

I was going to make an "Assimilation Program" type card where dead goblins grant your creatures with +1/+1 counters first strike, dead elves grant trample, and so forth, but it was really tricky to word in an economical way because Dissect is an ability word rather than a keyword.

Reverse Suffering - 3W
Sorcery
Until end of turn, whenever a creature enters the battlefield, you gain 3 life.
Each opponent returns all creature cards from their graveyard to the battlefield tapped.

Equality Edict - 2B
Instant
As an additional cost to cast ~, sacrifice X creatures.
Target opponent sacrifices X creatures.\\

Inspired by my recent play of Final Fantasy XV

• Ardyn's Edict 3RB
• Instant
• Target player sacrifices a creature, then they sacrifice a land, then they discard 2 cards from their hand.
• And THAT is why you're—-oh dear, dead, already? And I was just getting to the good part of my speech!

• Deadeye, Elder Behemoth 4GGGG
• Legendary Creature - Elder Beast
• Hexproof, Trample, Menace
• ~ Cannot be Countered.
• When ~ ETB, it deals damage equal to its power to each creature target player controls.
• When a creature your opponent controls dies after being dealt damage by ~, put a +1 / +1 counter on ~.
• 9 / 9

Lotus Fabricator - 7
Artifact
{T}: Create a colorless artifact token named Replica Lotus. It has "{T}, Sacrifice this artifact: add three mana of any one color."

Last Vestige
Land
~ enters the battlefield tapped.
When ~ enters the battlefield, sacrifice all other lands you control.
If a land would enter the battlefield under your control, put it into its owner's graveyard instead.
{T}: Add four mana in any combination of colors.

Last Vestige would be really good in a Myr deck.

Because most of those are mana dorks.

Dredbog, Mire of Despair
Legendary Land Creature - Swamp Shade
({T}: Add {B}.)
{B}{B}: ~ gets +1/+1 until end of turn.
1/1

Realistically I don't think a Legendary Land Creature would be printed (or if it did, it would probably be banned in EDH? I have no idea how the Commander Tax would work with land creatures) but it's an interesting concept. And here's the silly version:

Many Things
Legendary Enchantment Artifact Land Creature - Avatar
~ is all colors and has all basic land types.
1/1
It has become one with the mana, and thus its form is limitless.

Second one dies instantly because it's a creature that doesn't have stats.

Card tax:

Oblivion's Touch (1WUB)
Enchantment - Aura
Enchant permanent
Enchanted permanent loses all types, subtypes, and abilities, and has no power and toughness.
2WUB: Enchanted permanent becomes a 3/3 colorless Eldrazi creature with flying, vigilance and deathtouch until end of turn. Activate this ability only once per turn.

• Ardyn The Usurper 5RB
• Legendary Creature - Human Nightmare Horror
• You may cast ~ from exile or your graveyard.
• All Enchantments enchanting ~ lose all abilities.
• Tap, Destroy target creature.
• 6 / 5
• I am afraid the Planeswalking brought you hence, but it shall not deliver you forth.

• MA X Angelus-0 12
• Legendary Artifact - Vehicle
• Vigilance, Trample, Hexproof, Stampede (this creature cannot be blocked by creatures with power 2 or lower.)
• When ~ attacks, blocks or comes into play, deal 7 damage divided as you choose among creatures your opponent controls.
• Crew 8
• 14 / 14

Genocide - 7BB
Sorcery
Choose a creature type. Exile all creatures of that type. For each opponent, search that player's graveyard, hand, and library for all creature cards of that type and exile them, then that player shuffles their library. An opponent searches your graveyard, hand, and library for all creature cards of that type and exiles them. Then shuffle your library.

• Antonius of the Foul Oath 3WWBB
• Legendary Creature - Cleric
• Vigilance, Deathtouch
• All Clerics you control get +1 / +1 and you can tap 1 Cleric you control to prevent the next 3 damage to target creature or planeswalker you control.
• When you gain life and your opponent loses life at the same time, you can pay (1). If you do, put a 3 / 3 Black and White Demon Spirit creature token into play with Flying.
• 4 / 7

Commander; what sort of Commander Deck would this guy do the best with?

Hopemonger - 2W
Creature - Cleric Monger
{1}: Target player gains 4 life. Any player may activate this ability.
1/2
Wisdomonger - 2U
Creature - Wizard Monger
{1}: Target player draws a card. Any player may activate this ability.
1/2
Painmonger - 2B
Creature - Zombie Monger
{1}: Target creature gets -2/-2 until end of turn. Any player may activate this ability.
3/1

Shockmonger - 2R
Creature - Elemental Monger
{1}: ~ deals 2 damage to any target. Any player may activate this ability.
3/1

Sporemonger - 2G
Creature - Fungus Monger
{1}: Target player creates a 1/1 green Saproling creature token. Any player may activate this ability.
2/3

An attempt to make the 'monger' cycle a bit more useful. Yes, Monger is a creature type.

I feel like Shockmonger would make games end really super fast.

• Malhareff of the Eternal Horde 5WUB
• Legendary Artifact Creature - Zombie Sphinx
• Shroud, Flying
• When you play a non-creature spell, you may exile target creature card from either player's graveyard. Create a token that's a copy of it, except its a 5 / 5 Blue and Black Artifact Creature token with no mana cost.

• 6 / 6
• I have invested in you, stripling. Your rest ends.

• Sommerset the Spiteful Arbiter 4BBB

• If ~ would die or be put into exile from the battlefield, instead put it into its owner's library third from the top.
• 6 / 6
• Let the Gods quiver before the poison I set forth to plunder their potential.

Edited by NickTheSwing on Apr 12th 2019 at 10:33:03 AM

'All lands are Swamps' is basically an instant win against any non-black deck. Which is pretty wacky, even at 7 mana. Like, that'd almost certainly be insta-banned in Commander no matter what mana cost you put on it.

Self-Destructing Seedpod - GR
Creature - Plant
Cumulative upkeep {1}
At the beginning of your end step, target player gains control of ~.
When ~ dies, it deals damage to you equal to the number of age counters on it.
0/4
Its seeds also explode. How it actually reproduces remains a mystery.

Yeah, decided to add the nonbasic clause on there. I did kinda make Sommerset with Commander in mind, but I didn't take into account just how crippling his ability would be.

I don't think there's a Commander out there that interacts with life loss effects like Sommerset does.

The best interaction I can think of is Midnight Reaper and Reassembling Skeleton.
