Spider-Man India + Crystalline Crawler + Kor Skyfisher + Duskwatch Recruiter // Krallenhorde Howler

Spider-Man India

Crystalline Crawler

Kor Skyfisher

Duskwatch Recruiter // Krallenhorde Howler

How it works

1. Cast Kor Skyfisher by paying .
2. Spider-Man India triggers, putting a +1/+1 counter on Crystalline Crawler.
3. When Kor Skyfisher enters, it triggers, returning itself from the battlefield to your hand.
4. Activate Crystalline Crawler by removing a +1/+1 counter from it, adding .
5. Repeat.

This loop turns a simple self-bouncing creature into a continuous engine by exploiting the cost reduction from Duskwatch Recruiter's back face, Krallenhorde Howler, which discounts creature spells by {1} to make Kor Skyfisher cost just a single white mana. As Kor Skyfisher enters the battlefield, its trigger forces you to return a permanent, neatly picking itself back up while Spider-Man India takes advantage of the casting process to toss a +1/+1 counter onto Crystalline Crawler. That newly placed counter can then be immediately cashed in via Crystalline Crawler's ability to generate the {W} needed to cast Kor Skyfisher all over again, fueling an infinite storm count and endless enter-the-battlefield triggers.
