Make your own Magic card!

I figured as much. It just knocked me back on my heels because depending on the environment it sees play in, that would basically be "7: Win the game." for mono-green decks, and green would have no problem ramping into it.

I do love the flavor, though.

Maybe throw in some cumulative upkeep or something.

Or maybe something like...

Wild Overgrowth 2UGGGG
Enchantment
At the beginning of each turn, target land or artifact becomes a Forest.
Any player may 2 at any time to undo this effect to a land they control.
What was once unnatural has now been reclaimed.

Terraforming - 6UG
Enchantment
Choose a basic land in play. Enchanted land is a copy of it.

That can probably be cheaper, but I do like the idea of terraforming as an enchantment.

Shelter of the Trees G
Instant
As an additional cost to cast Shelter of the Trees, sacrifice any number of Forests.
Choose one—
* Counter target red or black spell unless its controller pays 2 for each Forest sacrificed to cast Shelter of the Trees.
* Prevent all damage target red or black creature would deal this turn unless its controller pays 2 for each Forest sacrificed to cast Shelter of the Trees.

EDIT: Wait, I have a better idea.

Shelter of the Trees G
Instant
As an additional cost to cast Shelter of the Trees, sacrifice any number of Forests.
You and each permanent you control gain protection from target red or black spell or permanent until end of turn unless the controller of that spell or permanent pays 2 for each Forest sacrificed to cast Shelter of the Trees.

Terraforming should cost about 3 at most to be even moderately useful. 8 is crazy.

High Apostle Eliezer 4WB
Legendary Creature - Vampire Cleric
Lifelink
Tap, Tap another cleric: Destroy target creature.
Tap another cleric: put target cleric permanent card from a graveyard onto the battlefield tapped under your control.
2/2

I really want there to be a WB legendary cleric...

Edit: Fixed.

You do realize that the second ability can bring back all Clerics in your graveyard at once by continiously tapping the most recent cleric you brought back, right?

I would suggest you change it so it brings the cleric back tapped.

Colorshift Zone
Land
{1}: Target permanent or spell becomes the color of your choice in addition to its other colors until end of turn. Any player may activate this ability. (The player who activated the ability chooses the color.)

You do realize you wouldn't be able to use that because everyone else'd activate it first, right? Needs an "only on his or her own turn" clause.

That's why I put "in addition". It doesn't tap, if that's what you're thinking. So they can't cancel it out or anything.

...Oh. :/ Thought it tapped to activate. Guess I misread it.

Form of the Angel 3WWW
Enchantment
At the beginning of your upkeep, return target creature in your graveyard to the battlefield.
You may have Form of the Angel deal 4 damage to a player at the beginning of the combat step. If you do, that player may choose to redirect that damage to a flying creature they control and deal combat damage equal to that creature's power to you.
At the beginning of each end step, your life total becomes 4.
Creatures without flying can't attack you.

Form of the Sphinx 3UUU
Enchantment
At the beginning of your upkeep, draw a card.
You may have Form of the Sphinx deal 4 damage to a player at the beginning of the combat step. If you do, that player may choose to redirect that damage to a flying creature they control and deal combat damage equal to that creature's power to you.
At the beginning of each end step, your life total becomes 4.
Creatures without flying can't attack you.

Form of the Hydra XGG
Enchantment
You may have Form of the Hydra deal X damage to a player at the beginning of the combat step. If you do, that player may choose to redirect that damage to a creature they control and deal combat damage equal to that creature's power to you. If you deal more damage than that creature's toughness, deal that much damage to the creature's controller.
At the beginning of each end step, your life total becomes X.

Form of the Demon 3BBB
Enchantment
As an additional cost to cast Form of the Demon, sacrifice a permanent.
At the beginning of your upkeep, you may sacrifice a permanent. If you do, destroy target creature and its controller loses 5 life.
You may have Form of the Demon deal 5 damage to a player at the beginning of the combat step. If you do, that player may choose to redirect that damage to a flying creature they control and deal combat damage equal to that creature's power to you.
At the beginning of each end step, your life total becomes 5.
Creatures without flying can't attack you.

Those are supposed to make a cycle with Form of the Dragon, right? I don't know where you're getting that combat step damage thing. You can't turn an existing card into a cycle, but then add a new effect to that cycle.

Form of the Statue - 7
Tribal Enchantment - Golem
At the beginning of your upkeep, you may destroy target creature with toughness 2 or less.
At the beginning of each end step, your life total becomes 7.
If you would be dealt damage, prevent all but 1 of that damage.

Form of the Transformer (2WUR)
Enchantment Artifact - Aura
At the beginning of each player's upkeep, choose one:

• Until end of turn, whenever you become the target of a spell or ability, counter it unless its controller pays {2};
• Until end of turn, whenever a creature attacks you or a planeswalker you control, deal 1 damage to that creature and you gain 1 life.

The idea being that either you're in vehicle form, and so are hard to notice, or you're in giant robot form and anything coming at you is going to get shot.

Also just noticed I wrote "creature" instead of "planeswalker". Oopsie.

Less ridiculously, if only slightly:

Vial of Tasty, Tasty Tears (1)
Artifact
Whenever a spell or ability you control counters a spell, gain 1 life.

It isn't done, but there's no reason why you can't do it. I changed it to that because the 5 damage at the upkeep thing is too red for the others to copy imo, but you need to be able to attack to emulate a creature.

If you want to keep track of how much was paid for X on a permanent (Form of the Hydra), you'll probably want to use counters of some kind. X in mana costs is 0 everywhere except on the stack (except for that one black card nobody wants to be friends with).

The original Form of the Dragon card has at least one white/blue mechanic. It's the kind of thing where flavour trumps mechanics.

Undeath Warden - 1WB
Creature - Human Cleric
Whenever a creature enters the battlefield or dies, you gain 1 life and target opponent loses 1 life.
1/1
In life there is energy. In death there is force. Yet so very few can fuel death with life.

Abzan Clanmage (WBG)
Creature - Hound Wizard
(2WB): Target player sacrifices a creature, then gains life equal to that creature's toughness.
(1GW): Target creature gets +1/+1 until end of turn for each +1/+1 counter on it.
2/2

Jeskai Clanmage (URW)
Creature - Djinn Wizard
(1UR): Draw a card. At end of turn, discard a card.
(2WU): Target attacking creature gains flying until end of turn. At end of turn, return that creature to its owner's hand.
2/2

Sultai Clanmage (BGU)
Creature - Naga Wizard
(2BG): Until end of turn, target creature gains deathtouch and "Creatures blocking or blocked by this creature have deathtouch".
(1UB): Each player discards a card and puts the top two cards of his or her library in his or her graveyard.
2/2

Mardu Clanmage (RWB)
Creature - Orc Shaman
(2RW): The next time target creature is dealt damage this turn, it deals that much damage to target creature or player.
(2BR): The next time target player loses life this turn, target player loses that much life.
2/2

Temur Clanmage (GUR)
Creature - Human Shaman
(1GU): The next time target creature deals combat damage to an opponent this turn, you may draw a card.
(1RG): Target creature you control gets +X/+X until end of turn, where X is its power. Sacrifice that creature at end of turn.
2/2

I think you may have goofed in the cost of one of the Abzan mage's abilities.

Oops. Yeah, turns out the costs that I posted for some of those abilities weren't what I had originally written down. Should be fixed now.

Specifically, the Abzan mage (still) has a casting cost of WBR and an ability with a cost of 1GW. I don't know that much about the clans, but I thought they were only three-color.

Oh, I guess it was his mana cost that was off, then. :/ Just realized. Thought it was odd, considering the ability messes with +1/+1 counters.

edited 18th Oct '14 7:47:12 PM by Knowlessman

facepalm

Ah. That's what you meant. I can't believe I missed that twice in a row. Fixed now, the Abzan mage is no longer in Mardu.

Still, though; neat idea, making guildmages for the clans. Not all the Guildmages had CMC 3-or-higher mana costs on their abilities (I know Azorius's had "Target creature flies" for WU), but then, a 2/2 at three colors should have more potent stuff than that.
