I think grav pull isn't very useful here. You only got 4 creatures and eventually want to use them as shield? And using them on enemies isn't to useful too as BB should definitely give you enough hp to eat everything.
So I removed them and tried to balance your deck a little. I changed mark to earth and removed 2 BB. You don't need 6 if you got so less creatures.
Instead I put in two acceleration which help you with the missing dmg which you can already use on a BB'd otyugh so when the delay is over it already has a nice atk.
Never put an Otyugh if you don't have a BB. You can give adrenaline to a 0 attack creature. It will "attack" 5 times, so it is ready in the 3th turn.
I'd use at least one adrenaline for an accelerated otyugh of course two is better. so use the remaining otyugh to stop enemy creatures.
The deck may have bad draws because you need to wait for BB, oty and adrenaline. So if you want at least to stop the delay of BB you can still use plate armor.
This would make adreanline less useful though.
Anyway, here's what I did, I hope it works. 5 creatures are still not much so you might/surely have bad draws sometimes.

Edit: You might get into trouble if your pulverizer gets destroyed and the enemy steals your shield
