Will Weavers

Creatures you control get +X/+X, where X
is the number of different colors of mana
spent to cast Will Weavers is. If Will
Weavers is two or less colors, instead only
dryads you control get +X/+X.
At the beginning of your upkeep, look at
the top X cards of your library and put
them back in any order. You may shuffle
your library.
