Staff of Domination + Cryptic Trilobite + Light of Promise + Spider-Man, Peter Parker

Staff of Domination

Cryptic Trilobite

Light of Promise

Spider-Man, Peter Parker

How it works

1. Activate Staff of Domination's second ability by paying 2 and tapping it, causing you to gain 1 life.
2. Spider-Man and Cryptic Trilobite trigger, putting two +1/+1 counters on Cryptic Trilobite.
3. Activate Cryptic Trilobite twice by removing two +1/+1 counters from it, adding CCCC that can only be spent to activate abilities.
4. Activate Staff of Domination's first ability by paying 1, untapping it.
5. Repeat.

This delightful engine revolves around Staff of Domination, which acts as the ultimate multi-tool once you have a way to generate infinite mana exclusively for activated abilities. Enter Cryptic Trilobite, whose restriction on spending its generated mana is completely bypassed by the Staff's various inexpensive activation costs. The real magic happens whenever you gain that single life, which triggers Light of Promise to pump the Trilobite with fresh +1/+1 counters to fuel its ability again—while Spider-Man, Peter Parker triggers simultaneously to add even more counters and grant indestructible protection to your creatures. By looping the life-gain and counter-replenishment, you can eventually cycle through the rest of the Staff's abilities to draw your deck, tap down opposing boards, and establish a completely unstoppable loop.
