Heaven Grimoire

While Hell Grimoire is in effect all Heaven
Grimoire Spells cost Nothing.
At the beginning of your upkeep, pick a Heaven
Grimoire spell from your hand to macro(macro
spells are instants and when cast are put randomly
inside your library after cast) if you
have no Heaven Grimoire spells search your
library for one and put it in your hand as a macro.
Heaven may look pretty, but its still filled with horrors
