A-Nashi, Moon Sage's Scion

Combat-damage triggers that peek at the opponent's deck are old ground; what sets this one apart is that it exiles from everyone's top card and prices the theft in life instead of mana. That second clause is the real design lever. Because you pay life equal to a spell's mana value rather than its cost, the payment scales with expense but ignores color and colorless requirements entirely: a five-mana bomb off the opponent's library costs five life, no lands untapped, no fixing required. It turns connected combat damage into an off-color, off-curve access engine, and because you also exile from the top of your own library, a card stays available even when the opponent's top is a Swamp. Ninjutsu is what makes the first hit reliable. Swapping the body in tapped and attacking off an already-unblocked creature sidesteps the sorcery-speed vulnerability a 3/2 for would otherwise face, and dodges the blocks and pre-combat removal that a face-up creature invites; the opponent still gets priority in the declare-blockers step, so the debut trigger is well protected but not untouchable. After that, the 3/2 attacks the honest way, and each subsequent connection refills the exile pool while the life total funds the next theft. Black has raided the top of libraries before, but those effects paid in mana and ground out value over turns. Here the ninjutsu delivery and the life-cost casting rebuild the approach around evasion and tempo, spending a total that only replenishes with help for spells you were never meant to reach.
