Goey, the Bard Knight

Vigilance

Whenever Goey, the Bard Knight enters the battlefield or attacks, you and the defending player each get a tune counter.

At the beginning of each player's upkeep, Knights you control get +X/+X until end of turn, where X is the amount of tune counters that player has.

{2}{g/w}{g/w}: Create a 2/2 white Knight creature token with vigilance.
