Spinerock Tyrant + Quasiduplicate

Spinerock Tyrant

Quasiduplicate

How it works

1. Cast Quasiduplicate by paying its mana cost targeting the creature that can recur spells.
2. When you cast that spell, Spinerock Tyrant triggers, copying Quasiduplicate and choosing Spinerock Tyrant as its target.
3. Resolve the copy of Quasiduplicate, creating a Spinerock Tyrant token.
4. Resolve the original Quasiduplicate, creating a token copy of the spell recursion creature.
5. When that token enters, it triggers, returning Quasiduplicate from your graveyard to your hand.
6. Repeat from step 1 one additional time, resulting in a total of five Spinerock Tyrants.
7. Cast the spell that creates a Treasure token by paying its mana cost, targeting any creature.
8. Each copy of Spinerock Tyrant triggers, copying that spell once for each Spinerock Tyrant you control.
9. Resolve all copies of that spell, creating at least one Treasure token each time.
10. Activate those Treasure tokens by tapping and sacrificing them, adding one mana per Treasure.
11. Cast Quasiduplicate by paying its mana cost targeting the spell recursion creature.
12. When you cast that spell, each copy of Spinerock Tyrant triggers, copying Quasiduplicate once for each Spinerock Tyrant and choosing the spell recursion creature once and Spinerock Tyrant as each additional spell's target.
13. Resolve all copies of that spell, creating two copies of the spell recursion creature and additional copies of Spinerock Tyrant.
14. When the first spell recursion creature token enters, it triggers, returning the spell that creates Treasure from your graveyard to your hand.
15. When the second spell recursion creature token enters, it triggers, returning Quasiduplicate from your graveyard to your hand.
16. Repeat from step 7.

This clever loop puts Spinerock Tyrant's ability to copy single-target instant and sorcery spells to work alongside Quasiduplicate. By leveraging the initial Spinerock Tyrant to copy Quasiduplicate and multiply your battlefield presence, you rapidly accumulate an army of tyrants that turn any targeted spell into an overwhelming storm of copies.
