While drafting WAR we encountered a situation we didn't know how to resolve. Imagine the following situation:
- The opponent attacks with Rising Populace and a 1/1 creature.
- I block the Rising Populace with Footlight Fiend and the 1/1 creature of the opponent with a 1/1 creature myself.
After the combat damage is dealt, the Populace gets a +1/+1 counter while I want to deal 1 damage to the Populace to kill it beforehand. Basically the triggers occur at the same time, so which ability resolves first? The Fiend's since I have priority? Will the Populace die or become a 3/3?
