The ShiftstonedEternal Power Calculator is a deck-building tool that visualizes your odds of drawing enough Influence and Power based specifically on the cards found in your deck.
long term I'd imagine you want to go more low to the ground. cut the throne wardens, the hammer of mights and the auric runehammers, add 4 whirling duo and 4 unseen commando. you're win rate wont necessarily spike by that much, but your deck caps out at 4 power then, and your games overall should be a lot faster. if you have the adventures, a Crimson Firemaw set instead of the Crownwatch deserter might be worth looking into if you're running into hailstorm too often. Also Pyroknights can be solid in a deck like this if you find your games going long and you end up facing against a wall of weenies. just ult it and smash over them. rakano aggro is quite good at flexibility so have a look at what decks / cards are causing you issues, and work around them accordingly.
