When a unit with a shield at Trifarian War Camp is affected by Smoke Screen and then Discipline, what is its final might?

Ruling: When calculating might modifications, apply all increases before all decreases. Smoke Screen's effect is calculated ("snapshotted") when the spell is played, not continuously recalculated.

Sequence:

• Start with base might (2 for the poro)
• Apply all increases: +1 from Trifarian War Camp, +1 from shield, +2 from Discipline = 6 total from increases
• Apply all decreases: -3 from Smoke Screen (snapshotted when played)
• Final might: 2 + 6 - 3 = 5 might

Nuances:

• If a second Smoke Screen is played after Discipline, it would only give -2 (not -3) because Discipline's +2 is already applied when the second Smoke Screen snapshots
• Aura effects like Trifarian War Camp don't use the chain to resolve and apply continuously
• The "increases before decreases" rule ensures aura increases like Trifarian War Camp apply before aura decreases like Green Leona
