Orochi Merge-Keeper card art
Orochi Merge-Keeper enters with a +1/+1 counter and then drops another counter on every creature you cast with modified status — that's a repeating counter engine stapled to a two-mana body. Chishiro, the Shattered Blade turns every aura and equipment into a trigger, which means Orochi Merge-Keeper is constantly firing; Marvin, Murderous Mimic copies modified creatures and keeps the chain going.

Orochi Merge-Keeper is a Commander card — the modified mechanic rewards creature-dense, counter-focused decks, and Commander's 100-card singleton format gives you the volume of modified payoffs to make the trigger fire consistently. In Modern and Pioneer it's legal but competing against faster, more redundant synergy packages where a 2/2 that conditionally distributes counters isn't pulling its weight. Legacy and Vintage don't want it at all; the power ceiling in those formats leaves incremental counter strategies far behind. Orochi Merge-Keeper's home is Commander, specifically any deck already built around +1/+1 counters or the modified keyword.
