Can Yasuo - Unforgiven move a teammate's unit in 2v2, including from their base to the battlefield?

Question

Accepted Answer

Yes — if Yasuo - Unforgiven's ability causes a Move (a spell/ability effect that moves a unit), it may target and move a teammate’s unit in 2v2 so long as the ability’s own wording and the normal Move legality rules allow it. However, you may not “issue Standard Movement” to a teammate’s unit (that is prohibited) — so if the effect tells you to make the teammate’s unit perform its Standard Move, that is illegal in 2v2.

An ability on Yasuo - Unforgiven that 'causes a Move' and targets a friendly unit can move a teammate’s unit in 2v2 because "friendly" includes your teammate’s controlled game objects [484.8.d] and spells/abilities can cause Moves [444]. That Move must still obey destination/origin legality (for example, you cannot move a unit to a battlefield that already has units from two other players) [444.2] [144.4.a.1]. If the card explicitly says to 'issue a Standard Move' (i.e., make the unit take its Standard Move action), that would be disallowed for teammate units in 2v2 [484.8.c.2].

Check the exact wording on Yasuo - Unforgiven to see whether the effect 'causes a Move' or instead instructs you to 'issue a Standard Move' for a unit. If the effect causes a Move and targets a 'friendly' unit, the teammate's unit is a legal target because 'friendly' includes your teammate's controlled game objects [484.8.d]. When the ability resolves, enforce any origin/destination restrictions the ability itself specifies per [444.1]. Ensure the destination battlefield is legal: a unit may not be moved to a battlefield that already has units from two other players [444.2] [144.4.a.1]. If the ability instead tells you to 'issue a Standard Move' to the teammate's unit, that is not allowed in 2v2 because players may not issue Standard Movement to their Teammate's Units [484.8.c.2].

If Yasuo - Unforgiven's text says 'target a unit you control' or 'target your unit', that wording would exclude your teammate’s units even though 'friendly' would include them — check the exact pronouns on the card. If the effect moves a unit to a non-board zone (banish, grave, etc.) and then a later effect attempts to play it to a battlefield, other rules about playing from non-board zones or pending finalization may apply (see relevant card interactions and timing rules not included in the supplied excerpts). If the ability causes the unit to perform its Standard Move (rather than simply moving it), the timing and Closed State restrictions on Standard Moves [144.1] might apply and the prohibition in 2v2 still blocks issuing Standard Movement to teammate units [484.8.c.2]. A battlefield that currently has a combat with two other players as participants is also an illegal destination for a Move from base per [144.4.a.1].

You must read the exact text on Yasuo - Unforgiven to determine which case applies. The 2v2 rules explicitly prohibit a player from issuing Standard Movement to their teammate’s units [484.8.c.2]. That means you cannot tell a teammate’s unit to take its Standard Move action. However, spells and abilities can cause Moves directly — and those caused Moves are not the same as 'issuing Standard Movement' unless the card text specifically tells you to issue the Standard Move [444]. "Friendly" includes your teammate's units, so an ability that says "move a friendly unit" or otherwise targets a friendly unit can legally target a teammate’s unit in 2v2 [484.8.d]. Any Move caused by an ability still must obey move legality: the source of the Move defines additional destination restrictions [444.1], and a unit may not be moved to a battlefield that already has units from two other players by any means [444.2] [144.4.a.1]. Therefore: If Yasuo - Unforgiven's ability causes a Move and targets a friendly unit, it may move a teammate’s unit (including from base to battlefield) provided the ability permits that origin/destination and the battlefield isn't blocked by the two-player limit. If instead the card's instruction is to 'issue a Standard Move' for that unit, that is disallowed in 2v2 because players may not issue Standard Movement to their teammate's units [484.8.c.2].
