Malcolm, Keen-Eyed Navigator + Magmaw + Unnatural Selection + Adrix and Nev, Twincasters

Malcolm, Keen-Eyed Navigator

Magmaw

Unnatural Selection

Adrix and Nev, Twincasters

How it works

1. Activate Unnatural Selection by paying 1, 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 loop turns Magmaw into a lethal engine by using Unnatural Selection to temporarily grant it the Pirate creature type, allowing it to trigger Malcolm, Keen-Eyed Navigator whenever it deals damage. Because Adrix and Nev, Twincasters doubles every token creation event, a single sacrifice by Magmaw generates two Treasure tokens instead of one—supplying more than enough mana to continuously recast the ability and fuel the loop indefinitely.
