Can cards that reduce might (like Stupify and Thousand Tail Watcher) reduce a unit's might to 1 even if it has buffs from Trifarian Warcamp or attached Buff cards?

Ruling: Yes, cards that reduce might to a minimum of 1 can reduce a unit to 1 might even if it has buffs from Trifarian Warcamp or attached cards. The reduction is calculated when the spell resolves by snapshotting the total reduction needed, which is then applied as a continuous effect.

Sequence:

• Calculate the unit's current might with all positive modifiers (base + buffs + battlefield effects)
• When a reduction spell resolves, calculate how much reduction is needed to reach the minimum (usually 1)
• Snapshot that reduction value
• Apply the snapshotted reduction as a continuous effect
• Positives are calculated before negatives

Nuances:

• If a unit leaves the battlefield after having might reduced, it loses battlefield bonuses and could end up at 0 might or lower
• Additional buffs applied after the reduction will increase might from the reduced value
