Coven Gathering

At the beginning of your endstep, untap all lands
you control.
Whenever you cast an Instant or Sorcery spell,
until the end of the turn, you may cast Creature
and Enchantment spells as if they had Flash.
{u}{g}: Uncover 1 (Look at the top card of your
library. You may put that card into your graveyard.)
