Stormchaser Chimera

A 2/3 flier that converts your library's contents into a swing of raw combat math, paying a repeatable activation to scry, reveal, and pump itself by exactly the revealed card's mana value. The design sits on top of two mechanics that pull against each other: scry lets you sculpt what the reveal finds, but the payoff rewards your most expensive spells sitting up next, which is precisely what smoothing curves usually tries to bury. A deck stacked with high-cost cards makes the attacks lethal but leaves the early turns clunky; a lean curve keeps the deck functional but caps the swing. The scry is the lever that cheats both directions: sink a land underneath before the reveal, or leave a fatty parked on top when you have already drawn enough action. Because the activation is open-ended and can be repeated at instant speed, the attack size is never fixed until you stop paying mana. What makes it unusual as a piece of evasion is that its ceiling is a function of the cards you chose not to cast this turn: a creature whose power scales with the deck's top-end rather than its own printed body. The +X/+0 is strictly offensive, leaving the 3 toughness untouched, so it stays an attacker that folds to most removal and trades poorly the moment it has to block.
