Thanks guys. I want a bit more feedback before I submit this for the crucible.
I made the Gravity Pull the Upped version because it functions as a direct counter to Gravity pull, and I don't want that card to have such a readily available counter without making the owner pay for it. I like it as a cheaper way to remove Gravity pull from one of your own creatures, like a Chimera. Playing this card so your chimera doesn't insta-die sounds like an advanced tactic, that ought to be relegated to a higher level card. Also, I dislike upgraded cards that are a straight improvement. I prefer cards like Minor Phoenix, or minor Abomination, that are a more fundamental change to the tactics employed by the card.
