Kenrith, Knight of Ardenvale

Adamant- If at least one mana of each color was spent to cast this spell, Kenrith enters the battlefield with 2 +1/+1 and a crown counter on him.
Whenever you cast a spell with adamant, if Kenrith
has a crown counter on him, the ability activates twice.
If you spend three or more mana of the same color
on a spell, draw a card.
