Lore Drakkis + Grinning Ignus + Time Warp

Lore Drakkis

Grinning Ignus

Time Warp

How it works

1. Cast Lore Drakkis for its mutate cost by paying U/RU/R, putting it under Grinning Ignus.
2. Lore Drakkis triggers, returning Time Warp from your graveyard to your hand.
3. Activate Grinning Ignus by paying and returning it and Lore Drakkis from the battlefield to your hand, adding CC.
4. Cast Grinning Ignus by paying 2.
5. Cast Time Warp by paying 3, causing you to take an extra turn after this one.
6. Repeat each turn.

This clever loop exploits the flexible nature of mutate stacks to recur and cast an extra turn spell indefinitely. By casting Lore Drakkis over Grinning Ignus, you trigger the former's ability to pull Time Warp right back out of your graveyard. From there, you use Grinning Ignus's self-bounce ability to net extra mana and scoop the entire pile back to your hand, leaving you free to recast Grinning Ignus, chain into Time Warp, and repeat the whole sequence on your next turn.
