I've always hated
Laboratory Maniac in any deck that I would personally make, as it's a
Grizzly Bears for 3 mana for most games, until you've already managed to combo off. Meaning it's literally the worst card you can draw during a game.
This on the other hand actually does something AND unlike
Laboratory Maniac which requires a draw card to make effective, this contains it's own way to win with no library.
Also even if people have creature removal, because it's a trigger that goes on the stack, you can still win even if it get's removed. With X=0 you don't even need any blue devotion to meet the criteria, as long as you literally have no cards in library.
I've managed to stop opponents from winning by killing or bouncing the
Laboratory Maniac in response to their draw card...not so anymore.
Laboratory Maniac is set to become relegated to the trash can, as most builds literally only require the one win condition, and although
Jace, Wielder of Mysteries is an option, because this costs only 2 mana and not 4 AND it's a creature for the purposes of
Dread Return for those decks that mill library, this is set to be the go to "no library wins".
Laboratory Maniac day is done and price will basically plummet.
