If I play Watcher and there's a Trifarian at play, do the units at Trifarian get the +1 still after Watcher's effect?

When you play Thousand-Tailed Watcher while enemy units are at Trifarian War Camp, the units do not "lose" the War Camp's +1 Might buff, but the interaction results in a snapshotted value that effectively overrides the continuous application of the War Camp's bonus for the remainder of the turn.

According to RiftJudge FAQ #1431:

• Thousand-Tailed Watcher snapshots the unit's current Might (which includes the +1 from the War Camp).
• It then applies the -3 Might reduction to that snapshotted value (to a minimum of 1).
• This result becomes the unit's new fixed Might value for the turn. Because the effect is snapshotted, the War Camp's lingering +1 Might bonus no longer applies to that specific value.

Example Sequence:

1. Unit starts at 2 Might.
2. Trifarian War Camp is active, making the unit 3 Might (2 base + 1 buff).
3. Thousand-Tailed Watcher is played. It snapshots the current 3 Might and applies the -3 reduction.
4. The unit's Might is set to 1 (3 - 3 = 0, but limited to a minimum of 1).
5. The War Camp's +1 bonus is no longer added to this new value.

Important Nuances:

• Moving away: If the unit moves away from the Trifarian War Camp after being affected by the Watcher, its Might will remain 1. The Watcher's effect has already snapshotted the unit's Might to a fixed value, and the War Camp's continuous bonus no longer applies to this value.
• Moving back: If the unit moves back to the Trifarian War Camp, its Might will remain 1. The Watcher's snapshotted value is fixed, and the War Camp's bonus does not re-apply.
• Future buffs: Any new Might modifiers applied after the Watcher's effect resolves (such as a spell that grants +1 Might) will apply normally to the snapshotted value. For example, a +1 Might buff would make the unit 2 Might (1 snapshotted + 1 new buff).
