Moat + Mystic Decree

Moat

Mystic Decree

How it works

1. All creatures lose flying and Islandwalk.
2. Moat prevents things without flying from attacking.
3. Creatures can not fulfill the conditions nessasary to attack.

This clever enchantment pairing completely shuts down the combat phase by exploiting how Magic’s rules of interaction handle keywords and combat restrictions. Mystic Decree strips every creature in play of its flying ability, neutralizing any native aerial threats. With all creatures now groundbound, Moat steps in to finish the job by prohibiting any creature without flying from declaring an attack. Together, they create an absolute combat lock that leaves your opponents entirely defenseless against your board.
