This clever synergy transforms Spike Feeder into a self-sustaining engine by capitalizing on its ability to spend its own counters for life. Each time you remove a counter to trigger its life-gaining effect, Spider-Man, Peter Parker swoops in with his passive triggered ability to immediately replace the lost +1/+1 counter on Spike Feeder. Because Spike Feeder's counter-removal can be repeated as long as counters remain available, and Spider-Man, Peter Parker perpetually replenishes that cost whenever life is gained, you loop the process to generate infinite lifegain triggers and infinite life.
