Uh… which tournament was this??? 
Sounds like a one-way trip to endless 
mirrors. 
For the curious, the tournaments I’ve run have been:
- Conquest-style where everyone’s stable is
, 
, and 
. (Oh, the In-Humanity! [Single Day Tournament]) - Standard CP style where only non-human characters were allowed (Rook, Arg, Lum, BBB, Perse, Gwen, Ven, and Troq). (Oh, the In-Humanity! [Single Day Tournament])
- Conquest-style where each person chose a stable by picking one character from each pair of Yomi’s siblings (Grave or Jaina, Gwen or Gloria, Menelker or Midori). (Sibling Rivalries [Single Day Tournament])
- Double blind random rolls for every single game (SUPER SERIOUS SATURDAY [Single Day Tourney])
- A conquest style tournament with pre-made stables that roughly emulated the canonical alliances of Yomi lore (Fractured Factions [Single Day Tourney]).
All have been single day, Bo5, and fast timer.
