Treetop Freedom Fighters

The trick here is what happens after the trade. A 2/1 with haste is fragile by nature: it swings immediately, then dies to the first blocker or the first removal spell willing to spend on it. But the enters trigger has already banked a 1/1 white Ally token by the time any of that resolves, so the exchange nets you a body no matter how the combat math shakes out. That token, not the haste, is what carries the card. It hedges against the usual weakness of cheap red aggressors, keeping a creature on the board, a go-wide count intact, and a sacrifice input available even after the front body is gone. The red-into-white color bleed matters too: seeding a white Ally into a red shell points the design at Rebel and Ally tribal aggro that wants both a fast clock and a widening board. This is honest common-to-uncommon aggro glue, a two-for-one on a stat line cheap enough to curve into and built to be replaceable rather than to snowball. Nothing about it asks you to build around it; it asks you to attack, and to keep attacking once the first creature is dead.
