This clever sequence turns Triskelion into a self-sustaining engine of growth and destruction by leveraging Strength of Will to shield it from its own firepower. When Triskelion shoots itself for 1 damage, Strength of Will triggers to place a +1/+1 counter on it for each point of damage dealt, which is then amplified into a net gain of counters thanks to the replacement effect of Kami of Whispered Hopes. Because you generate more counters than you spend to activate Triskelion's ability, you can continuously pump its power and spray infinite damage at any target.
