Ooze is OP overall though. Look at all the basic cards, then look at ooze, lol. 3/2 for 2 is already ok, the battlecry is too powerful. In some ways it's a better tech card than Harrison if you don't care about the card draw or that drawing is bad for you in the deck you're playing. Against classes that don't have a weapon, a 2 mana 3/2 is a lot better than 5 mana 5/4.
I think they made the new ooze for arena, since they think weapon classes, specially warrior can be too strong now if they get all the weapons and the chances of you getting a anti weapon card in arena is quite low. So here have another one.
