Companion -- Each card in your starting deck
has an activated ability. (If this card is your chosen companion, you may cast it once from outside the

Whenever you activate an ability, if it isn't a
mana ability, you gain 1 life. If it's the third time
this ability has resolved this turn, draw a card.
{1},{t}: Target creature can't attack this turn.
