Can Emperor's Divide move units from 2 different bf to base at the same time?

Question

Accepted Answer

No. Emperor's Divide moves units from a single battlefield (it says “a battlefield”); it cannot simultaneously move units from two different battlefields.

When you play Emperor's Divide, you choose one battlefield to affect and may move any number of your friendly units at that single battlefield to their bases. The card’s text uses the singular “a battlefield,” so it does not allow selecting units from two different battlefields in the same play.

You play Emperor's Divide (an Action you may play on your turn or in showdowns). The card instructs: “Move any number of friendly units at a battlefield to their base.” When resolving the spell you choose which battlefield (one battlefield) to apply the instruction to, then move any number of your friendly units that are at that chosen battlefield to their bases. You cannot pick units from a second, different battlefield as part of the same resolution because the spell’s text specifies a single battlefield (singular). If the movement causes game-state changes that involve Showdowns (for example, per [446] a Move can open a Showdown), those rules apply after the Move is performed.

If multiple of your units occupy a single battlefield, you may move any subset or all of them to base with one play of Emperor's Divide because the effect allows "any number of friendly units at a battlefield." You can play Emperor's Divide separately for two different battlefields by casting it twice (subject to game resource limits), but a single play cannot affect two distinct battlefields at once. If moving those units interacts with Showdown/Contested status (e.g., making a battlefield contested or empty), use the Move and subsequent state-resolution rules such as [446] and the cleanup staging rules in [344] and [FAQ:unleashed#6].

The ruling is based on the card text for Emperor's Divide which reads: “Move any number of friendly units at a battlefield to their base.” The use of the singular phrase “a battlefield” indicates the effect applies to one battlefield chosen when the spell is resolved. The Core Rules context provided does not contain any general rule that would allow a card that names a single battlefield to instead affect multiple different battlefields simultaneously, so the most defensible reading is that you choose one battlefield and move any number of your units at that battlefield to their bases. Additionally, because the spell can be played in showdowns and moves units, any resulting Showdown-related consequences follow the normal rules — for example, Moves can open a Showdown under [446], and Showdowns are staged/opened according to [344] and the clarification in [FAQ:unleashed#6]. If you want to affect units on two different battlefields in one game turn, you must cast two separate copies of Emperor's Divide (or use another effect that explicitly allows moving units from multiple battlefields), since nothing in the provided rules or the card text permits selecting multiple distinct battlefields with a single play.
