Barad-dûr, the Dark Tower

If you own this card in your game, you have to own
Mount Doom and The One Ring in your game, too.
When Barad-dur, the Dark Tower enters the
battlefield, destroy two target nonland permanents.
All orcs and nazgul you control get +1/+1.
{t}: Add {b} or {r} to your mana pool, if Barad-dur
is equipped with the one Ring he transforms.
"Then at last his gaze was held: wall upon wall,
battlement upon battlement, black tower of adamant,
he saw it: Barad-dur, Fortress of Sauron.
All hope left h
