If a Watcher gives opponent's units -3M and then you Charm one of their 1M Recruits to a Trifarian Warcamp (which gives +1M), does the unit become 1M or 2M?

Ruling: The unit would become 2M. When the unit changes control and moves to the Warcamp, the -3M effect is locked in at -0M (since the unit was already at minimum 0M), and then the Warcamp's +1M is applied on top of that.

Sequence:

• The Watcher's -3M effect reduces the 1M Recruit to 0M (minimum)
• When Charmed to the Warcamp, the -3M effect is locked at -0M at the moment of resolution
• The Warcamp then applies +1M
• Final result: 1M base + 1M from Warcamp = 2M
