Syr Vondam, the Lucent

Deathtouch on a single attacker threatens whatever blocks it; deathtouch handed to your entire board threatens the idea of blocking at all. That is the axis this design lives on. The trigger fires on two distinct events, entering and attacking, which in practice means an anthem the moment it arrives, then again every combat step it charges into. Each firing gives the rest of the team +1/+0 and deathtouch until end of turn, and the direction of that trigger is what defines it: the reward points outward at attacking, not inward at defending, so a wall of blockers gets no benefit while an army swinging sideways becomes lethal. The +1/+0 is trivial arithmetic in isolation, but wed it to deathtouch and a one-power token trades up into anything, forcing the bad choice: eat a blocker or take the hit and bleed out. There is no trample here, so a defender can still chump a single attacker; the math is that they run out of bodies faster than you run out of swings. Lifelink and deathtouch sit on the body itself, letting it stabilize while it leads the charge, though only the deathtouch and the power bump extend to the team. This is the go-wide white-black payoff those decks have wanted for years: a repeatable, board-wide combat anthem that makes a swarm lethal without a sacrifice loop or a combo line, just creatures pointed at a face.
