How it works
Activate Staff of Domination's second ability by paying 2 and tapping it, causing you to gain 2 life.
Cleric Class and Cryptic Trilobite trigger, putting two +1/+1 counters on Cryptic Trilobite.
Activate Cryptic Trilobite twice by removing two +1/+1 counters from it, adding CCCC that can only be spent to activate abilities.
Activate Staff of Domination's first ability by paying 1, untapping it.
Repeat.
This charming engine relies on Staff of Domination's life-gaining activation to fuel a perpetual cycle of growth and mana production. By turning your colorless mana into life, you trigger Cleric Class and Light of Promise, which pump up Cryptic Trilobite with fresh +1/+1 counters. You can then strip those counters away using Cryptic Trilobite's special ability to generate the restricted mana needed to untap Staff of Domination and pay for the next life-gaining loop. Once this positive feedback loop is humming, you can easily pivot the extra mana into infinite card draw, infinite life, and total control of the board.
