Vadrok, Apex of Thunder + Peregrine Drake + Quasiduplicate + Snap

Vadrok, Apex of Thunder

Peregrine Drake

Quasiduplicate

Snap

How it works

1. Cast Vadrok for its mutate cost by paying 1W/U, merging it under Peregrine Drake.
2. The Peregrine Drake mutated creature's ability from Vadrok triggers, casting Quasiduplicate from your graveyard without paying its mana cost.
3. Resolve Quasiduplicate, creating a token copy of the Peregrine Drake mutated creature with haste.
4. The token copy of the Peregrine Drake mutated creature triggers, untapping five lands you control.
5. Cast Snap by paying 1, returning the nontoken Peregrine Drake and Vadrok from the battlefield to your hand and untapping two lands you control.
6. Cast Vadrok for its mutate cost by paying 1W/U, merging it under the token Peregrine Drake mutated creature.
7. The token Peregrine Drake mutated creature triggers once for each of its Vadrok abilities.
8. Resolve one of these triggers, casting Quasiduplicate from your graveyard without paying its mana cost.
9. Resolve Quasiduplicate, creating a token copy of the Peregrine Drake mutated creature with haste.
10. The token copy of the Peregrine Drake mutated creature triggers, untapping five lands you control.
11. Resolve a second trigger from step 7, casting Snap from your graveyard without paying its mana cost, targeting the mutated creature that includes the nontoken Vadrok.
12. Resolve Snap, returning Vadrok from the battlefield to your hand as well as multiple token creatures which cease to exist, and untapping two lands you control.
13. Resolve any remaining triggers from step 7, casting any noncreature cards with mana value 3 or less that were not already cast since step 7 from your graveyard without paying their casting costs.
14. Repeat from step 6, adding one additional token Vadrok to each new iteration of the Peregrine Drake mutated creature token.

By leveraging Vadrok, Apex of Thunder's mutate ability over Peregrine Drake, you turn every subsequent creature transformation into a recursive engine that recasts your graveyard. Each time you mutate, Vadrok's trigger lets you deploy low-mana spells for free, specifically utilizing Quasiduplicate to multiply your drake-and-dragon stack while generating a massive surge of mana via the original Drake's entry trigger. Snap then resets the board by bouncing your pieces back to hand while untapping your lands, allowing you to replay Vadrok onto a fresh token copy and endlessly compound your triggers for infinite storm count, magecraft triggers, and land untaps.
