FREE: Mtg white 10 cards

I want a white card to give me massive health. Like dbl My health, so if im at like 23, i would be bumped to 46 health against My opponent(s). I need a card to clear the playing field on all-sides, just in case one of My opponents has many more higher attack creatures or just way too many smaller. I need a creature that will gain a +1/+1 modifier everytime i gain health so i can create a strong attack/defense creature. Also need a card that will let me gain +1 health every round, prob an artifact. And whatever else in white mana. Thats ehat i need :)
