Whenever you put a +1/+1 counter on a creature you control, choose one. You may choose both if you sacrifice a creature and pay an additional {G}{U}{B}. Target creature you control gets +2/+2 and has deathtouch until the end of the turn. Target creature you don’t control is dealt 2 damage. If a creature gained a +1/+1 counter this turn, draw a card and discard a card. {/fontsize-2}
