Akashia, Thaumaturgist

Vigilance, flying, first strike, trample.
When you cast a spell from your hand, if that
spell is black and white, you gain 3 life; if that
spell is black and blue, you may draw a card
and discard a card; if that spell is black and red,
Akashia causes 3 damage to any target; if that
spell is black and green, create a green Elephant
3/3 token. If that spell has three or more colors,
double those effects.
