If my opponent casts Thousand Eyes Watcher (which sets might to 0), then in combat I buff my 1 might recruits with Back to Back (+2 might), what is the final might value?

Ruling: The units become 3 might. Negative might effects are snapshotted at resolution, so the -0 might effect from Thousand Eyes Watcher is locked in at the time it resolves, and subsequent buffs apply normally.

Sequence:

• Thousand Eyes Watcher resolves, setting might to 0 (this effect is snapshotted)
• Back to Back is cast, granting +2 might
• Final result: 1 (base) + 2 (Back to Back) = 3 might
