When each turn starts, if you put 2 or more Subordinates into any arena last turn, choose an arena. Each of your Subordinates in the chosen arena gets +1 power, Precision, and "Attacks from this unit can't be disrupted." until end of turn.

Precision
Precision: An isolated, static ability that means, "This unit cannot be intercepted." An attacking unit with Precision cannot have the target of its attack changed by a unit with the Intercept ability. "Elude" is the former name of this keyword. Treat any unit with Elude as if it has Precision instead.
