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.
What's the thought behind the Blitrocks? They're decent on their own I guess but they don't interact with any of the rest of your deck. It has no way to give deadly or double damage, and doesn't really ramp to the point where it shoots big things down reliably, either. Can I assume they're replaceable?
Blitrok is a good card that gives a lot of value, and has a useful ping effect that can be very helpful. You can copy cards with Hawk that Blitrok creates, and Blitrok can sometimes give a good card out of nowhere which is useful. Other than that, yeah you can replace it if you want to. I am never upset to have Blitrok in hand in this deck, but if you were to chuck Blitrok I'd say add an extra spellshaper, Qirin Ascendant, and then a flex spot. Or all three a flex spot. Up to you.
