I don't recommend cubing Brash Taunter. It might not even be that good, but it is much better than it looks like and really feels horrbile for the opponent. If they can't remove it, that is, which is not too unlikely with indestructible. The problem is, if you just sit there and wait, it will deal you easily 3 or more damage eot every round. And if you attack into it with a non evasive creature, it will just deals two chunks of damage to you. You can barely race it and you can't play slowly against it either. You have a indestructible-beating removal or hope to somehow have more life AND an evasive creature. Because even when you have a large flyer, that stupid gobbo will deal at least as much damage. So often you need a removal or at least two evasive creatures. Not to mention that it kills all your X/1s.
And that is all when youdon't pump it. At first I thought it seems like a fun card. After playing a few games against it I know the opposite is the truth. It is easily in my top 5 most hated cards, horrible design. God, I hate this card.
