Neyali, Suns' Vanguard

Token strategies have always fought the same math problem: a swarm of small bodies deals a lot in aggregate but converts terribly against blockers and lifegain, and each individual token is close to worthless. This design attacks that on both axes at once. Double strike on every attacking token doubles the damage of a board built to go wide, turning a race into a rout, while the exile trigger means the swarm pays you for its own aggression rather than emptying your hand. The card advantage clause is more disciplined than it looks: attacking a single player with a wide team exiles exactly one card, so the engine scales across opponents rather than across bodies. And the permission is more generous than it reads: the exiled card can be played (a land played for turn, a spell cast) on any later turn you also attacked with a token, and it stays exiled until you do, so the buffer you build never spoils. What keeps the 3/3 honest is that both effects hang on tokens specifically and on attacking specifically: a control shell cannot borrow the engine without committing to the aggressive plan the card was built around. This is the go-wide payload that gives a Boros tokens deck a reason to be Boros: red supplies the token generation, white supplies the anthems and the bodies, and this ties them into a single closing threat that refuels itself as it swings.
