Back to the Basics is a really old-style double-elimination RBY tournament: everything legally obtainable is allowed. That includes Mewtwo (and Mew). That includes Double Team. We're going to battle it out like it's 1999...literally (only with Netbattle instead of the PBS).
Other rules of note:
* Sleep clause must be enabled.
* Self-KO clause must be enabled.
* Species clause is in effect.
* 6-on-6, no Stadium mode (Stadium didn't even come out until 2000).
* No Surf Pikachu/Raichu or Amnesia Golduck, as these were from Stadium.
* PP Ups must be on, unless both players wish to have them off.
* Beyond that, anything goes!
Winners' Bracket:
Mizuno vs [kd8]otome
Obi vs Giga Punch
Losers' Bracket:
Warthog vs Sandslash
spies vs Pilocus
Groudon80 vs Darkbolt
SSBM Roy vs Carl
