Can you tell me the rulings for Confusion in the Ranks?
user
0. The exchange isn't optional. If there is a legal choice, you must make one.
1. Confusion in the Ranks triggers on itself entering. If an opponent controls an enchantment, exchange Confusion in the Ranks for that enchantment.
2. Even though Confusion in the Ranks triggers only when an artifact, creature, or enchantment enters, the ability can target a land if the permanent entering is an artifact land.
3. The permanents are exchanged only if they're both on the battlefield when the ability resolves.
4. The permanents have to share a permanent type both when the target is chosen and when the ability resolves.
