My shard after Palp event... (strategy question)

I'm also in a Jan '17 shard. My plan is to speed up my Boba and possibly a little more potency. Sometimes I think a bug occurs and the game makes my Boba attack a taunter on other turns even tho he is supposed to be able to ignore taunts. Ability block plus the squishyness of EP means with any luck at all, my Boba will take him out. If they have Dooku, my Boba might get stunned on his counter and that could definitely ruin my strategy. I just started farming Rex too, but it will be long after EP shows up in arena that I will be able to use him.
