Make your own Magic card!

Hmm, that gives me a closely related idea.

Quad Damage 1RRR
Instant
Target creature gets +X/+0, where X is its power, and double strike until end of turn.

Critical Strike (R)
Enchantment - Aura
Enchant creature
Whenever enchanted creature attacks, flip two coins. If you win both flips, double all combat damage enchanted creature would deal this turn.

Amulet of Pain (2)
Artifact
If an opponent would lose life, you may instead put that many charge counters on ~.
(T), Remove X charge counters from ~: Target opponent loses X life.

Amulet of Mercy - 2
If an opponent would lose life, you may instead put that many charge counters on ~.
{T}, remove X charge counters from ~: Target player gains twice X life.

x3 *Hit

No, Critical Hit would probably be an Instant. Critical Strike is a common term used for skills and talents that increase critical-hit rates.

Amulet of Pain intended for multiplayer?

Amulet of Pain + literally anything that can put charge counters on an artifact = extra damage. Gilder Bairn or Vorel of the Hull Clade if you're particularly impatient.

Soothing Mantras - W
Enchantment
During each upkeep, each player gains 1 life.
Even those of darkest heart find themselves muttering the words in times of distress.

Actually, I came up with the idea for Amulet of Pain as I was building a deck for this guy, since you can't always give your guys flash. Though the proliferate shenanigans also work nicely.

Oh yeah. You could also smack your opponent with a lightning bolt and then ration out the points of damage so that you can always trigger bloodthirst abilities.

Amulet of Pain + Doubling Season.

And in addition to the damage you deal normally being doubled, you could use the amulet's own ability to double it each turn. How's THAT for quad damage? Yeesh.

Great Doubling - 4WUBRG
Legendary Enchantment
If a player would gain life, that player gains twice that much life instead.
If an effect would make a player draw cards, it makes that player draw twice that many cards instead.
If an effect would make a player sacrifice permanents, it makes that player sacrifice twice that many permanents of that type instead.
If a source would deal damage to a creature or player, it deals double that damage to that creature or player instead.
If an effect would put one or more tokens onto the battlefield or counters on a permanent, it puts twice that many of those tokens on the battlefield or of those counters on that permanent instead.

I speak for the trees.

Shouldn't he be legendary, flavor-wise? He's The Lorax, after all.

Soulfire Coil 1W
Enchantment
Whenever another permanent you control becomes the target of a spell or ability an opponent controls, you may shuffle it into its owner's library.

Lear, Aging King 2WR
Legendary Creature - Human
When Lear enters the battlefield, choose three other creatures. Randomly exile one of those creatures. Each other chosen creature gets a +1/+1 counter.
Lear gets three time counters. Remove one at each end step. If Lear has no time counters, creatures exiled by Lear return to the battlefield. If a creature returned to the battlefield this way dies, sacrifice Lear.
"...that she may feel— / That she may feel / How sharper than a serpent’s tooth it is / To have a thankless child." - —William Shakespeare, King Lear
2/2

Edited.

Would it just be that turn, or would you have to remember every creature he's gotten lost that way?

Suspend and two counters would do the trick for the exiled creature.

To go with the Capitalism and Communism cards from a few pages back, have an Objectivism card.

Objectivism (3BBB)

Legendary Enchantment

When ~ ETB, exile up to three target creatures on the field. For each creature exiled, gain a 0/1 Artifact Creature token named Gold with "Sacrifice this card: Add one mana of any color to your mana pool".

During your upkeep, summon one Gold token.

When a Gold you control is sacrificed, each opponent loses 1 life.

Not sure if this is worded correctly.
