If I play Thousand Tail Watcher and my opponent plays Grand Stratagem, do the -3 Might still apply to the tokens (making them 3 Might instead of 6)?

Ruling: The order matters. Watcher reduces Might by 3 to a minimum of 1 when it resolves. Buffs applied after Watcher increase Might from its current value, while buffs applied before Watcher get reduced.

Sequence:

• If Grand Stratagem resolves first: tokens get buffed to 6 Might, then Watcher reduces them to 3 Might
• If Watcher resolves first: tokens stay at 1 Might (can't go below minimum), then Grand Stratagem buffs them to 6 Might

Nuances:

• Snapshotting applies: playing Watcher against tokens that haven't received bonus Might yet does essentially nothing, as the Watcher effect snapshots to -0 for all of them (they're already at 1 Might minimum)
