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.
How often are you sending Channels at face rather than units? It seems like with fewer Duelist Blade in the main you would need to go face more with Channel.
Channel face is not usually essential but sometimes can be necessary to steal a win. The majority of times I will channel units and let the blade chip them down 4 at a time.

Yeah the deck is quite flexible I currently like stray to deal with dawn walkers and tokens but you can put in lightening storms to deal with tokens and aggro or more feeding times to deal with dawn walkers. You could also play devastating setback which acts as a sweeper and a spell removal. Other cards commonly in the main board are rain of frogs for control and lightening strikes for scream/weapon strategies.
