Ouiba, Patience of the Umbrar

Cards in Stasis you control have hexproof for as long as Ouiba remains untapped.
Enchantments you control cost {1} less to target with spells and abilities your opponents control while Ouiba is tapped.
{g}{u},{t}: You may cast any number of cards in your hand with Stasis without paying their mana cost and cast them into Stasis.
"Our power ebbs and flows, the key is knowing when to advance and when to lie in wait."
-Ouiba
