Gravitic Punch + Kalamax, the Stormsire + Fury Storm

Gravitic Punch

Kalamax, the Stormsire

Fury Storm

How it works

1. Cast Gravitic Punch by paying its mana cost, targeting Kalamax.
2. Holding priority, cast Fury Storm by paying its mana cost, targeting Gravitic Punch.
3. Kalamax's first and second abilities trigger.
4. Resolve the first ability, creating a copy of Fury Storm targeting the original Fury Storm.
5. Resolve the second ability, putting a +1/+1 counter on Kalamax.
6. Resolve the Fury Storm copy, creating a copy of Fury Storm, targeting the original Fury Storm.
7. Kalamax's second ability triggers, putting a +1/+1 counter on itself.
8. Repeat from step 6 any number of times.
9. Once you have an arbitrarily large Kalamax, have the final Fury Storm copy target Gravitic Punch. This'll create two copies of Gravitic Punch in addition to the original Gravitic Punch.
10. Resolve all Gravitic Punches, dealing infinite damage to each of up to three opponents.

This explosive loop turns Kalamax, the Stormsire into a lethal powerhouse by leveraging the way storm and copy mechanics interact on the stack. By casting Fury Storm to target an initial Gravitic Punch, Kalamax’s triggered abilities allow you to continuously copy Fury Storm while steadily growing its own power with +1/+1 counters. Once Kalamax reaches an arbitrarily large size, you redirect the final Fury Storm copy back to Gravitic Punch, creating multiple copies of the sorcery that let you hurl massive chunks of damage directly at your opponents.
