Lullmage Mentor + Anointed Procession + Mondrak, Glory Dominus + Elspeth, Storm Slayer

Lullmage Mentor

Anointed Procession

Mondrak, Glory Dominus

Elspeth, Storm Slayer

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.

This spell-locking engine turns a single countermagic effect into a self-sustaining army by leveraging a compounding token-multiplication network. When you use Lullmage Mentor to tap seven untapped Merfolk and counter an opponent's spell, its triggered ability normally grants just one 1/1 token—but the stacked replacement effects of Anointed Procession, Mondrak, Glory Dominus, and Elspeth, Storm Slayer exponentially multiply that single creation event into eight fresh bodies. With that sudden influx of Merfolk, you instantly replenish your tapped workforce to recast the counterability on the very next spell your opponents attempt, creating an unbreakable lockdown.
