Lamplight Slinker

Terrorize {2}{u}{b} (You may cast this card as though it had flash if you pay its terrorize cost. If you do, put it on the bottom of your library at the beginning of the next end step.)
When Lamplight Slinker enters the battlefield, if its terrorize cost was paid, you may reveal the bottom card of your library and put that card into your hand. Each player loses life equal to its converted mana cost.
