Infernal Kirin

Discard built on convergence rather than selection. The trigger keys the discard to the mana value of whatever Spirit or Arcane card you just cast, and it fires the moment you put that spell on the stack, before it ever resolves: cast something for two, and the targeted player reveals their hand and ditches every two-drop in it. That makes it a stripper that wants reach across the curve, not depth at one number, since a second cast at the same cost finds nothing left to take. The hand empties by hitting different values on different turns, so a varied spread of costs, not a tight cluster, keeps the effect live. It leans on the splice-onto-Arcane engines of its era for tempo, though the leverage there is mostly that splice lets a single cheap cast carry a fistful of stacked effects while still firing the Kirin once, since spliced text is added to the original spell rather than cast separately. The 3/3 flier is incidental, a clock to ride behind the hand attack rather than the reason to run it. As disruption it is conditional in a way targeted hand attack is not: it never sees the hand to choose, so it whiffs entirely against costs you cannot match, and it idles on any turn without a Spirit or Arcane spell to cast. That blind, value-gated discard is the price for the upside, an effect that rewards a deck disciplined enough to keep firing the right spells at the right numbers.
