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.
On reddit you asked for feedback so I thought I would add. It looks like a good Rakano Aggro deck that perhaps only lacks in some consistency areas. The first thing I would add would be merchants of one kind or another. Ixtun Merchant for consistency within deck or Red Canyon Smuggler if you want a diversity of answers and a good body. You could move Ankle Cutter to the Market if you feel he's weaker and Deep-Forged Plate Could be moved to the market as well. If you add Ixtun merchant, you could add another Icaria to the Market if you want more of her or the same for any of the Onis. The market also allows for certain cards that can be helpful for certain situations, like Bore against Relic based decks or Flameblast to close out a game where you draw a bunch of power. There are a variety of different takes on markets - take a look at some other fire or rakano markets to get a good idea of some good cards people usually stick there. The limitation with Red Canyon Smuggler is that then the market can only have cards NOT already in your deck (like if you took Deepforged Plate out of the deck and into the market is would be fine, but a 3rd Icaria would not).
In other words, the next step for your deck is markets. They really do help. Best of luck and thanks for brewing!
I agree that you should try markets if you haven't already, but I'm not convinced they are the obvious or even necessary improvement path for this deck. If you were to add merchents, than red canyon smuggler is the only one that makes sense, and you can move Icaria and plate into your market and cut the ankle cutters to make room for the smuggler. I, however, tend to lean towards no-merchant decks for linear aggro, so long as there is consistency and power. I would try to run 3 workshops but otherwise, with the possible exception of Icaria, completely avoid running less than four of any card, I would also run Oni samurai. I would probably cut the defiances altogether, counting on torch and finest hour to beat the little guys and focusing on just having too many oni for them to deal with. Alternatively, if you think you need to draw a kyojun to win, then definitely run Ixtun merchant, even If it's really just 3 more copies of kyojun
