Other artifact creatures you control get +1/+1
for each color among spells you cast this turn.
Whenever an artifact creature you control dies,
gain 1 life, scry 1, each opponent loses 1 life,
draw a card then discard a card if the card you
drew was not an artifact card, then put a +1/+1
counter on target artifact creature you control.
