Centaur Omenreader

Kor Skyfisher

How it works

2. Spider-Man India triggers, putting a +1/+1 counter on Crystalline Crawler.

This ingenious engine transforms a simple bird into a self-sustaining loop by leaning on cost-reducers and modular mana sources. With Centaur Omenreader tapped to make creature spells cost {2} less, Kor Skyfisher can be cast entirely for free, triggering Spider-Man India to continually empower your board while the Skyfisher's own entry triggers force it right back to your hand. Meanwhile, Crystalline Crawler acts as our battery, easily absorbing the counters gifted by Spider-Man India and converting them back into the white mana needed to satisfy Kor Skyfisher's alternative casting costs if the reduction isn't enough, or simply churning out an infinite storm count and repeatable enters-the-battlefield triggers.
