Whirlwind, Killer Cyclone

The evasion here is priced on tempo, not board development. Menace and unblockable riders usually gate on the attacker itself; this one instead punishes a defender for the crime of showing up too slowly, stripping a blocker off the attacked player for the whole combat. The trigger keys off freshly arrived creatures swinging in, so the haste on its own 2/3 body is the seed: attack with threats that came down this turn and one of the target opponent's creatures can't block. Read the timing carefully, though, because it changes how you build. The ability fires "whenever one or more" such creatures attack a player, so it resolves once per attacked opponent per turn, not once per attacker. Flooding six hasty bodies into one player still removes exactly one blocker; the extra commitment buys damage, not additional evasion. That makes this a scalpel, not a mass-evasion effect, a way to punch a single specific creature through the wall rather than dissolve the wall. In multiplayer the wording does open a wider reach: attack several opponents with turn-arrived creatures and each of them loses a blocker, one apiece. Red and its allies have circled attack-triggered blocker denial for years; the wrinkle here is the narrow window of creatures that arrived the same turn they swing, which is precisely why haste is doing structural work rather than just hurrying the beatdown.
