By giving Triskelion lifelink, you create a self-sustaining loop where every ping from its native ability directly feeds back into its own power. Removing a +1/+1 counter to deal 1 damage to any target triggers the life-gaining requirement for Spider-Man, Peter Parker, whose ability instantly replaces the spent counter with a fresh one. This elegant loop lets you machine-gun down any combination of targets while generating infinite life and continuous lifegain triggers.
