Slurrk, All-Ingesting

Most +1/+1 counter commanders punish you for losing creatures; this Ooze pays you for it. The trigger keys on death, not survival: whenever a countered creature you control dies (Slurrk included), everything else carrying a counter grows. That inverts the usual math of a counters deck, where a chump-block or a removed body is a setback. Here a creature that dies with a counter on it is a payment, and the survivors swell to collect it. The 0/0 printed body is a delivery mechanism rather than a liability: it walks in held together entirely by five counters, so the moment it is killed or sacrificed, it feeds its own engine. Marry that to a sacrifice outlet and you can cash in a single expendable body on demand, redistributing its worth across a wide board. The timing is what disciplines the payoff: the survivors have to still be around when the trigger resolves, so a symmetrical board wipe offers nothing to grow, and the engine wants controlled, one-at-a-time deaths rather than mass carnage. The requirement that the dying creature had a +1/+1 counter is what forces commitment to the theme: you have to seed the board with counters before the deaths mean anything, which stops it from being a plug-and-play aristocrats payoff. Partner lets a second legendary commander join it, which is where the shell gets rounded out. What Slurrk wants is a counters deck built to lose creatures on purpose, a design goal most +1/+1 counter commanders actively steer away from.
