Malcolm, Keen-Eyed Navigator + Magmaw + Imagecrafter + Doubling Season

Malcolm, Keen-Eyed Navigator

Magmaw

Imagecrafter

Doubling Season

How it works

1. Activate Imagecrafter by tapping it, causing Magmaw to become a Pirate until end of turn.
2. Activate Magmaw by paying 1 and sacrificing another nonland permanent, dealing 1 damage to an opponent.
3. Malcolm triggers, creating two Treasure tokens.
4. Activate a Treasure by tapping and sacrificing it, adding 1.
5. Repeat from step 2.

This clever loop turns Magmaw into an unlikely plundering scoundrel with the help of Imagecrafter, which paints Magmaw as a Pirate so its damage-dealing ability satisfies Malcolm, Keen-Eyed Navigator. Every time Magmaw hurls a nonland permanent at an opponent, Malcolm triggers to generate a Treasure token, which is instantly doubled into a pair of Treasures thanks to Doubling Season's replacement effect. Sacrificing one of those newly minted Treasures funds Magmaw's activation cost while leaving the extra token behind to build an escalating supply of mana and infinite damage.
