Lullmage Mentor + Anointed Procession + Primal Vigor + Exalted Sunborn

Lullmage Mentor

Anointed Procession

Primal Vigor

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.

This mesmerizing setup locks your opponents out of the game entirely by weaponizing the rules of token multiplication. When you activate Lullmage Mentor to counter an incoming spell, its own triggered ability normally rewards you with a single Merfolk token, but the combined replacement effects of Anointed Procession, Primal Vigor, and Exalted Sunborn transform that solitary token into a flood of eight fresh bodies. With that exact threshold met, you instantly have enough creatures to tap for the next activation of Lullmage Mentor, creating a self-sustaining loop that counters every spell your opponents cast while generating near-infinite creature enter-the-battlefield triggers.
