Lullmage Mentor + Anointed Procession + Primal Vigor + Mondrak, Glory Dominus

Lullmage Mentor

Anointed Procession

Primal Vigor

Mondrak, Glory Dominus

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 loop turns a single counterspell into a self-sustaining wave of Merfolk by leveraging an exponential token-doubling engine. When Lullmage Mentor counters an opponent's spell using its activated ability, its own triggered ability creates a 1/1 Merfolk creature token, which is instantly multiplied by Anointed Procession, Primal Vigor, and Mondrak, Glory Dominus. Because these replacement effects stack to multiply the generated tokens by sixteen, tapping those newly minted Merfolk easily refills your mana-and-tap reserves to counter the next spell in perpetuity.
