I just had a moment of inspiration.

Zhalfirin Hero

Quicksilver Lurker
Creature - Fish (U)
Whenever Quicksilver Lurker deals combat damage to a player, extract 2. (Look at the top two cards of an opponent’s library, exile one of them, then put the rest on the bottom of his or her library in a random order.)
When Quicksilver Lurker dies, draw a card for each creature card it extracted.

I really really like this mechanic.

Me too, but isn't the keyword up to X (or Y with the X-skip?)

Edit: Oh wait, there's a bolded X in there. Carry on I guess.

Flameslasher --
Creature - Elemental
First strike
Whenever ~ zones, target creature gets +2/+0 and gains haste until end of turn.

Theorycraft

Sorcery (U)
Draw two cards, then discard a card.
Archive (After this spell resolves, you may put it on top of its owner's library instead of into that player's graveyard.)

Arc Weld
Instant
Arc Weld deals 2 damage to target creature or player.
Build (The next instant or sorcery spell you cast has all of this card's text except for any Build ability, in addition to that card's other text)

Ugh, I don't know how to word this. The basic idea is pre-splice, so normally you just get the card's effect twice, but if the next spell you cast also has build, than you get to carry over the original effect another time, and so on and so forth.

Boar Youth
Creature - Boar Common
Charge 2 (When ~ enters the battlefield, you may have it get +2/+0 and gain haste and trample. If you do, at the beginning of the end step, sacrifice ~.)
1/1

Great Vine |
Creature - Plant Wall
Reach, defender
Delicious (When this creature dies, you may exile it. If you do, gain life equal to it's toughness).
0/8

Claims Denier
Creature - Squid Wizard (R)
Flash
Elicit (You may pay this card's elicit cost any time you could cast it. If you do, put it from your graveyard onto the battlefield, then exile it.)
When Claims Denier enters the battlefield, return target spell to its owner's hand. (It doesn't resolve.)
2/2

Djinn Initiate U
Creature - Djinn Monk
Flying, Prowess

Menacing Sheriff |
Creature - Human Rogue

Vigilance, Grit (This creature gets +X/+0 where X is the amount of damage it is currently suffering. X cannot be more than its toughness.)
