When Smoke Screen is played during a Showdown at Trifarian War Camp, does the +1 might bonus from the Battlefield apply before or after the -2 might from Smoke Screen?

Ruling: The unit becomes 1 might. Additions are always calculated before subtractions, so the Trifarian War Camp bonus applies first, then Smoke Screen's debuff is applied.

Sequence:

• Player A's 2 might unit gains +1 might from Trifarian War Camp (becomes 3 might)
• Smoke Screen applies -2 might debuff for the entire turn
• Final result: 1 might
