Mystic Barrier + Court of Vantress

Mystic Barrier

Court of Vantress

How it works

1. At the beginning of each of your upkeeps, Mystic Barrier and Court of Vantress triggers twice if you aren't the monarch, or once otherwise.
2. Resolve the Mystic Barrier trigger, choosing "left".
3. If you aren't the monarch, resolve the Court of Vantress triggers, causing you to choose "right" and choosing to keep it as a copy of Mystic Barrier.
4. Otherwise, resolve the Court of Vantress trigger, creating a token copy of Mystic Barrier, choosing "right" as the copy enters the battlefield.
5. As long as there are three or more players in the game, creatures cannot attack.

By stacking multiple instances of Mystic Barrier with opposing directional choices, you can effectively create a total combat lock that stops all creature attacks in multiplayer games. The first enchantment forces attacks in one direction, while Court of Vantress steps in to duplicate that exact restriction in the opposite direction. Whether Court of Vantress copies the barrier directly or spawns a token copy depending on your monarch status, the overlapping constraints leave your opponents with no legal targets to attack.
