The Blue Moon

At the beginning of your upkeep, create a token
that's a copy of all creatures you control. If you
do, destroy all tokens you control up to the
amount of non-token creatures you control.
Whenever a spirit is dealt damage from any
source, if you control a token that is a copy of
it, you may phase it out. If you do, deal that
damage to a token that is a copy of it. Or, you
may pay {3}{w/u} and deal that damage +2 to
target creature your opponent controls.
