Queen Azshara

Servant of N'zoth — All cards in your hand gain Megamorph {x}, where {x} is the mana value of
the card.
Schemes of the Naga — Whenever a face-down
card you control would be destroyed, if it's a non-creature card you may exile it. You may play
that card until end of turn.
"I know your dreams, your lust for power. Refuse, and
you will be crushed beneath the tides!"
