Vegard - Guiding wanderer

Riot, Hexproof
{2}{r}{g} Vegard cannot be blocked
Whenever Vegard's owner sings the chorus of a
song and at least one other player sings with him,
he gets to put one +1+1 counters on up to
two creatures and players singing with, puts up
to one +1+1 counter on any target creature,
untap that creature.
Play this only once every turn and as a sorcery.
For every twist along the road was an opportunity to explore.
