Yeah, patron is awful, they waste the entire 90s when they are on 2 health and no chance in killing me. I have to keep hearing, "Git in here!"
I love how arena can sometimes give you new ideas. Got a Cogmaster's Wrench in a rogue draft so decided to make a Oil Mech deck and it has been surprisingly effective. Been playing a good bit of oil rogue and hero power only having two charges is a bit of a drag sometimes, like especially when your opponent has a taunt minion. The wrench having 3 charges is perfect.
