When Stand United is played, does it increase each Buff from +1 Might to +2 Might for the turn, and do the Buffs return to +1 Might when the turn ends?

Ruling: Stand United gives a unit a Buff (if it didn't already have one) and makes all your Buffs give +2 Might instead of +1 Might for the turn. When the turn ends, all Buffs return to their normal +1 Might.

Sequence:

• Stand United is played
• Target unit receives a Buff if it didn't have one
• All Buffs you control become +2 Might for the turn
• Turn ends and all Buffs return to +1 Might

Nuances:

• Each existing Buff on a unit (such as 7 Buffs on Lee Sin champion) gets the +1 bonus, effectively doubling the Might contribution from Buffs for that turn
