This clever loop uses Cryptic Trilobite as a self-sustaining mana engine, turning its own growth into the fuel needed to keep going. By removing a +1/+1 counter from Cryptic Trilobite to generate restricted mana, you can pay for Juju Bubble's life-gaining activation ability. Each time that life is gained, Spider-Man, Peter Parker triggers to place a fresh +1/+1 counter right back onto Cryptic Trilobite, completely replenishing your battery. While Juju Bubble's trigger condition requires you to sacrifice it whenever you play a card, simply leaving it untouched allows this cycle to generate as much life as you desire.
