"Will they nerf weapon removal to promote the new legendary weapons?" Here's your answer.
Most of the weapons don't care if you remove them or aren't terrible even if you do. You just ramp up the druid (and the 1 extra attack every turn isn't too bad), Paladin and Rogue just cycle, Hunter gets his battlecry anyway, Warrior will get at least one recruit off, Shaman will get one spell.
This is probably the second worst ooze card overall as it is. Even Bloodsail Corsair is better I think.
This is ok I guess. good card for arena but in constructed is outvalued really, Gluttonous ooze does the same thing for less mana and gives you some armor and then Harrison Jones has the same cost with just 1 less health and draws you cards, and then for new/F2P players I think the vanilla ooze is still better, this one has no added effect so it's just a bigger vanilla ooze so running the old cheap 2 ooze is better imo, you spend less man, can come out earlier and as neither of them have an added effect is just better to be more mana efficient, the body is nice but I don't think nice enough to justify it.
