How it works
- Activate Arixmethes by tapping it, adding .
- Activate Arixmethes by paying 1 and untapping it, giving it +2/+2 until end of turn.
- Repeat.
By tapping Arixmethes, Slumbering Isle for its generous two-mana output of {G}{U}, you generate more than enough fuel to kick off this sequence. Umbral Mantle equips for free and grants the creature an untap ability, which Biomancer's Familiar cleverly discounts from {3} down to just {1}. Because Biomancer's Familiar also features a tap ability that resets adapts, its presence firmly anchors the creature-centric nature of the engine while Umbral Mantle and Arixmethes, Slumbering Isle loop infinitely to pump out boundless green and blue mana alongside an infinitely massive sea serpent.
