Etriossa, God of Tribute

As long as a player has paid less than 4 life this turn, Etriossa is not a creature.
Whenever a player pays life, put a +1+1 counter on this card, then both players draw a card.
Players may pay 2 life to pay for {1} in the mana costs of spells they cast.
"Hollow is the rich man's soul, for all his weight is rested in his greedy heart."
