Charlo, Chromatic Crafter

Whenever you cast a spell, for each color of
mana spent this way :
{b/g} - Put a -1/-1 on target creature.
{r/w} - Target creature gains Flying or Lifelink
until end of turn.
{u} - Scry 1, draw a card then discard a card.
Those abilities can only triggers once each turn.
"Playing 3 colors is easy, so much options"
