Hallar, the Firefletcher + Triumph of the Hordes

Hallar, the Firefletcher

Triumph of the Hordes

How it works

1. Cast Triumph of the Hordes by paying 2
2. Cast the spell with kicker or multikicker by paying its mana cost plus its kicker cost at least once.
3. Hallar triggers, putting a +1/+1 counter on it, then causing each opponent to get a number of poison counters equal to its power.
4. Each opponent loses the game.
