(Transforms from Aclazotz, Deepest Betrayal.)
{T}: Add {B}.
{2}{B}, {T}: Transform Temple of the Dead. Activate only if a player has one or fewer cards in hand and only as a sorcery.
If a card that isn't a transforming double-faced card is a copy of Aclazotz, Deepest Betrayal, it won't return to the battlefield when it dies.
The last ability of Temple of the Dead will resolve even if you have two or more cards in hand at that time.
