Beast Attack

Two 4/4s out of one card, both at instant speed, both arriving in response to whatever the opponent has just done: that is the trade this is built around. The token rate is unremarkable on its own, but the flashback cost turns one slot into eight power across two bodies spread out over the game. The triple-green commitment on each half is the price of that flexibility, and it asks for a deck swimming in green sources with mana to spare in the late game. The flashback clause does the structural work a buyback spell does elsewhere, except it spends a turn between casts rather than escalating the cost, which suits a Beast at instant speed: hold it to ambush an attacker, then dig it back out of the graveyard to rebuild after a sweeper. Instant timing on both casts is what makes the surprise real, letting the Beast show up mid-combat instead of telegraphing itself a turn ahead the way a creature card would. This is a green attrition tool wearing a beater's clothes, designed for the grinding midrange mirror where the last player still holding threats takes the game.
