Mystic Reflection + Exalted Sunborn + Storm Herd

Mystic Reflection

Exalted Sunborn

Storm Herd

How it works

1. Cast Mystic Reflection either from your hand by paying 1 or from exile for its foretell cost by paying , choosing Exalted Sunborn.
2. Cast Storm Herd by paying 8, creating a number of 1/1 Pegasus creature tokens equal to twice your life total that enter as copies of Exalted Sunborn due to Mystic Reflection.
3. Whenever you create one or more tokens, you will instead create 2^X times that many tokens, where X is the number of Exalted Sunborns you control.

This astonishing cascade begins by casting Mystic Reflection to target Exalted Sunborn, setting up a replacement effect so that any subsequent creature entering the battlefield arrives as a copy of that magnificent angel instead. Then, you cast Storm Herd, which initially tries to flood the board with tiny Pegasus tokens based on your current life total. However, because Mystic Reflection turns those incoming creatures into copies of Exalted Sunborn—and Exalted Sunborn itself features a static ability that doubles the creation of any tokens under your control—the resulting exponential chain reaction spirals completely out of control.
