Enthralling Performance -- When Firbolg Flutist enters the battlefield, gain control of target creature you don't control until end of turn. Untap it. It gains haste and myriad until end of turn. (Whenever it 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.)

Whenever equipped creature attacks, put a +1/+1 counter on it and tap up to one target creature defending player controls.

Equip {W} ({W}: Attach to target creature you control. Equip only as a sorcery.)

While an opponent is choosing targets as part of casting a spell they control or activating an ability they control, that player must choose at least one Flagbearer on the battlefield if able.

Whenever Sunhome Enforcer deals combat damage, you gain that much life.

{1}{R}: Sunhome Enforcer gets +1/+0 until end of turn.

Haste

Whenever Éomer of the Riddermark attacks, if you control a creature with the greatest power among creatures on the battlefield, create a 1/1 white Human Soldier creature token.
