Be sure to follow the rule before you head out.
Rule: You must post before you leave.
The only games in which Black Lotus is legal is so that those who own an original have a place to play it.
It (and all the big Type A Tourney Guns) gives a considerable edge to whoever draws it, so games are better served by both players just agreeing not to play it.
