This elegant loop is set into motion the moment you gain a point of life, which prompts Spider-Man, Peter Parker to place a +1/+1 counter on Scurry Oak. That influx of counters makes Scurry Oak churn out a 1/1 Squirrel token, and the arrival of that new token immediately rouses Trostani, Selesnya's Voice to restore your life total. Because that fresh burst of lifegain satisfies Spider-Man, Peter Parker all over again, the sequence loops indefinitely to flood the board with infinite creature tokens, infinite +1/+1 counters, and infinite life.
