Grismold, the Dreadsower
The generosity is a trap. On your end step this hands a 1/1 Plant to each player, an evenly distributed gift that reads as cooperative but is really seeding fuel for a single accumulator. The third line is where the symmetry breaks: when any creature token dies, from any source, on any side of the table, the +1/+1 counter goes to Grismold and only Grismold. That converts the entire board's token attrition into a private growth engine. Every Plant thrown in front of a blocker, every token sacrificed to an outlet, every 1/1 lost in a swing pumps the one 3/3 in the room whose trample keyword ensures the accumulation actually reaches a face. The whole build-around turns on a nasty asymmetry: the same effect that populates opposing boards also stocks the pantry for a one-sided payoff, and that payoff only pays if the Troll survives the culling, since the counters have nowhere to land if he is not on the battlefield when a token dies. That pairs the card most naturally with sweepers calibrated to spare a modest body while erasing a field of 1/1s, a wrath that kills the fodder and immediately feeds the survivor. It is a growth engine you deliberately share with your opponents, handing out the resource you intend to weaponize against them. The counters are locked in once placed, so the accumulation is a ratchet, never a reset.
