I feel confident about this ruling however need a better way of clarifying my understanding to others. And yes, I know Hypothermia is suspended/banned now.
In an Iyslander vs. Warrior matchup
Warrior is active player and hits with a weapon (before resolution). Refraction bolters triggers and goes on the stack. Then priority passes to the Iyslander player, they decide NOT to respond to bolters trigger. Warrior resolves bolters by destroying to give Go Again to weapon. Can Iyslander respond to the destruction by playing Hypothermia from arsenal?
Thanksn
