Ender Chest

When Ender Chest enters the battlefield, exile
the top X cards of your library.
As long as you control Ender Chest, cards exiled
by Ender Chest can be cast as if they were in
your hand and as if they had flash.
{2}, {t}: Exile the top card of your library.
Inside this mysterious chest is a void of items that can
be accessed from anywhere.
