Use the warcry units to build your own huge midgame monster. Save the pump spells to make favorable trades during combat because the AI will never see them coming. The Torches and Swords of Icaria are to keep the coast clear for your units. Vanquish gives you a shot against huge units like Sandstorm Titan coming out.
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.
I like this. Btw, since you are running 27 power, how do you feel about replacing 4 Fire Sigils with Shugo Standard instead? Then you can free up Daring Maneuver for x4 more units? I feel that 24 is a bit too low.
