Munchkin Apocalypse in a Tournament

[Jarl Wilm]

The Tournament rules don't have anything about Apocalypse yet, and I'm running a tournament in February. Discussing Munchkin Cthulhu, the tournament rules state: Tournament Rounds which use only
Munchkin Cthulhu cards – at all tables –
may use the “More Scary Cultist Rules.”
Rounds that combine Cthulhu with other
sets, either at a single table or with different sets
at different tables, should not use those rules, to
avoid disparity in Tournament Levels. In either
case, whether those rules are used should
be announced to all players, and (if the rules are used)
the rules should be explained before the games begin.

Since the Seventh Seal has the same sudden-death potential as the "More Scary Cultist Rule," does that mean we shouldn't use Apocalypse in tournaments; that we shouldn't use the Seals in tournaments; or that we should only play Apocalypse in tournaments where every table is playing either Munchkin Apocalypse or Munchkin Cthulhu?
