Schlonev, Bard-barian

Eminence - As long as Schlonev, Bard-barian is in the command zone or on the battlefield, whenever you cast a barbarian, put a verse counter on it.
{2}{r}{g}, {t}: Creatures you control with verse counters on them gain your choice of First strike, Haste, Rampage 2, or Provoke.
He's a warrior yes. But rather aggressive and he plays music. No one knows what he is...
