brainstorm:
- cards that work well with all PW's.
- cards that work with Frey's abilities.
- ramp spells for lands and land auras, rather than ramp creatures and artifacts, to offset ramp loss if my PW's elves die.
- big mana spells (not just big creatures) and x spells
- light on arts and enchants to go heavy on art+chant removal (things like tranquility)
- army: some tokens + overruns as well as some big creatures
