Seriously my minion battlecries should not buff enemy minion board while in combat. Like orc-estra minion buffed enemy team minions while in combat from beast deathrattle…gave them +40/40 and lost because of that .
This isn’t a bug. Orc-estra Conductor’s battle cry is “Give a minion +2/+2. Improve your team’s future Orc-estra Conductors.” It does not specify that the minion has to be friendly. You probably should not play it next to Rylak
If the minion was restricted to your board only then you wouldn’t be able to buff the tavern.
