How does Stand United interact with buffs on Lee Sin, Ascetic, and how is his Might calculated when buffs are added or removed after Stand United resolves?

Ruling: Stand United makes buffs give +2 Might instead of +1 Might for the rest of the turn. When calculating Lee Sin's Might, count all buffs at their current value (+2 each while Stand United is active), then apply any fixed reductions like Smoke Screen.

Sequence:

• Step 3 (after Stand United): Lee Sin has 5 base Might + (4 buffs × 2) - 4 from Smoke Screen = 9 Might
• Step 5 (after spending a buff with Wallop): Lee Sin has 5 base Might + (3 buffs × 2) - 4 from Smoke Screen = 7 Might

Nuances:

• Smoke Screen's reduction is fixed/snapshotted when it resolves and remains that value for its duration, even if the unit gains more Might later
• Lee Sin, Ascetic can receive buffs from any source; the "if it doesn't have a buff" reminder text on other cards is just default behavior that his ability overrides
• When calculating with "minimum" effects, use the snapshotted values from when those effects resolved
