This lovely angel enters with two Shield counters, so it has pretty good protection making it a great target to buff up, but the real draw is the trigger on entering or attacking where we can remove one counter from our creature (ANY creature we control that is) or planeswalker to draw a card
Play with some of the most dominating Magic cards ever, whether you're into Commander, Pioneer, Legacy, or all of the above
It will have haste until another player gains control of it (or, in some rare cases, gains control of the creature spell itself)
It's an Elemental so it's not bad in Tribal decks like Omnath, Locus of the Roil
Most of the noncreature spells can draw cards, so you'll never run out of action in your hand with how many cards you can draw in a turn
