Lullmage Mentor + Parallel Lives + Elspeth, Storm Slayer + Exalted Sunborn

Lullmage Mentor

Parallel Lives

Elspeth, Storm Slayer

Exalted Sunborn

How it works

1. Whenever an opponent casts a spell, activate Lullmage Mentor by tapping seven untapped Merfolk, countering that spell.
2. Lullmage Mentor triggers, creating a total of eight 1/1 Merfolk creature tokens.
3. Repeat.

To lock down the stack completely, Lullmage Mentor provides a way to counter opposing spells by tapping seven untapped Merfolk you control. While doing so normally requires a steady supply of bodies, Parallel Lives, Elspeth, Storm Slayer, and Exalted Sunborn stack their replacement effects to exponentially multiply every token you receive—turning the single Merfolk token triggered by Lullmage Mentor into eight fresh bodies at once. This explosive generation ensures you easily break even on the seven-Merfolk cost, netting extra tokens with every counterspell to instantly refuel the loop and seal the game.
