Eminence — At the beginning of combat on your turn, if Arahbo, Roar of the World is in the command zone or on the battlefield, another target Cat you control gets +3/+3 until end of turn.
Whenever another Cat you control attacks, you may pay . If you do, it gains trample and gets +X/+X until end of turn, where X is its power.
This commander's eminence ability is a triggered ability. The commander must be on the battlefield or in the command zone as the trigger event occurs and also as the triggered ability resolves. If the commander is in an appropriate zone as the trigger event occurs but leaves that zone, the ability won't do anything as it resolves.
