Lullmage Mentor + Anointed Procession + Mondrak, Glory Dominus + Doubling Season

Lullmage Mentor

Anointed Procession

Mondrak, Glory Dominus

Doubling Season

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 potent control lock turns Lullmage Mentor into an inescapable counterspell engine, using its own activated ability to trigger its token-generating condition whenever an opponent casts a spell. While the Mentor's tap ability requires seven Merfolk, the math quickly spirals out of control thanks to Anointed Procession, Mondrak, Glory Dominus, and Doubling Season acting in concert. Instead of creating just a single Merfolk token, these replacement effects compound exponentially to produce eight tokens per counterspell, easily leaving you with a surplus of creatures to tap for the next threat. As a result, your opponents are locked out of resolving any spells while your board floods with an overwhelming army.
