Is there any place where they’ve announced the winners and decks?
Mana crypt was printed around late 1995 I think, I can’t remember if it was legal or not, but there were plenty of decks that could use it.
MirrorU decks could have considered 1-2, as they often needed to damage themselves for the mirror kill.
Some zoo decks ran ernham, serendibs, and serras, so they could have considered it.
Mono-artifact was pretty rare, at least in the tournaments I went to, but it might have worked well.
As I mentioned before, I did see it in some pretty fast Atog decks (cursed scroll, vice, bolts, factories, etc), but that wasn’t till 1996?
Academy decks were extremely fast and likely would have preferred some extra mana.
Tinker and Welder were popular decks, albeit much later.
I’m not saying it was optimal, but maybe just overlooked because people evaluated cards differently then?
I think if we replayed Vintage these days (free plug: http://www.themanadrain.com/topic/2795/vintage-redux-a-new-format-for-your-consideration) we would find that it was way more playable than we thought.
The best old decks that could utilize mana crypt back in the day were shops, I think. Juggies, Su-Chi, Trike...workshop + mana crypt meant a stream of 4/4 or 5/3 threats from turn 1 forward.
