Play little nerds and clog up the board to waste your opponents time while you both build your mana base. Ideally drawing tons of cards from your manuscript and Land Surveyors / Apprentice Wizards. You have lots of blockers and trebuchet operators with border militia so you can fling zombies or any big cards drawn too early at any important enemy minions. Finish your opponent off with craterizes, major explosions, a charging clansman, or a doomsday device (just pray you have a bodyguard around when the timer runs out.)
Notable combos woven into this mess:
Grandmaster Wizard standing on a Geistwood uses a pact with the devil
Pact + River of Flame
Manuscript + Zombies + Lots of mortals + Prince
(Obvious) Bodyguard actually can protect multiple things
Occult Ritual + Standing stones + lots of small minions
Trebuchet + critical mass of expensive cards
