Captivating Performance ? When Firbolg Flutist enters the battlefield, gain control of target creature you don't control until end of turn. Untap that creature. It gains haste and myriad until end of turn. (Whenever that creature attacks, for each opponent other than defending player, you may create a token that's a copy of that creature that's tapped and attacking that player or a planeswalker they control. Exile the tokens at end of combat.)
