Slurrk enters with five +1/+1 counters on it.
Whenever Slurrk or another creature you control dies, if it had a +1/+1 counter on it, put a +1/+1 counter on each creature you control that has a +1/+1 counter on it.
Partner (You can have two commanders if both have partner.)
Slurrk is a mono-green +1/+1 counter engine that snowballs your whole board: load creatures with counters, then sacrifice or trade them so every counter-bearing creature grows. You build a wide, counter-laden board over a few turns, then crash in for lethal combat damage or overrun the table once your team gets out of hand. Partner lets you pair Slurrk with a second commander to add an outlet, a sac engine, or another color.
Add counter doublers (Hardened Scales, Branching Evolution, Doubling Season) and free sac outlets (Ashnod's Altar, Goblin Bombardment) to make the death trigger fire repeatedly and explosively. Choose a Partner that supplies what mono-green lacks—an aristocrats payoff, removal, or a sacrifice engine—and tighten ramp with fast mana like Sol Ring and mana dorks. Top-end finishers (Craterhoof, Pathbreaker Ibex) plus protection like Heroic Intervention guard against the board wipes that otherwise undo the whole plan.
