Holy Wrath seems weird here. The average damage is about 5 2/3, though if you exclude the Molten Giants, it's closer to 4.5. So you're dealing a damage and a half more than Hammer of Wrath on average (excluding the cases where you draw a Giant and it's massive overkill on a dude), and you won't know what the expected damage is until you've already chosen the target, so it's extremely difficult to use properly. Sure, there'll be times where you face-check someone with it and miracle a Giant and they die, but it's too unreliable. I'd much rather see Quartermasters, Hammers of Wrath, Azure Drake, Defenders of Argus, or something else in place of it.

Also Dr. Boom seems better than Cairne and Ysera seems better than Alexstraza.

Edit: Oh yeah and Tinkmaster is terrible. Mind Control Tech, Black Knight, Ironbeak Owl, Harrison Jones, or really anything else seems better than it.
