Lullmage Mentor + Adrix and Nev, Twincasters + Primal Vigor + Exalted Sunborn

Lullmage Mentor

Adrix and Nev, Twincasters

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 delightful combination turns a single counterspell into an overwhelming tidal wave of Merfolk by leveraging multiple token-doubling effects at once. When Lullmage Mentor taps its assembled followers to counter an opponent's spell, its own triggered ability normally generates just one token, but the combined replacement effects of Adrix and Nev, Twincasters, Primal Vigor, and Exalted Sunborn compound exponentially—multiplying that single token into eight fresh combatants. Because you now control more than enough creatures to immediately pay the activation cost again, Lullmage Mentor can continuously neutralize every subsequent spell your opponents cast while flooding the board with an endless army of tokens.
