GoldfishA copy of this deck that never acts. There is no opponent to choose.
Who goes first?

Who goes first alternates duel by duel. The results measure the bot as much as the deck: both sides are played by the same heuristics.

This deck has 25 copies the rules engine can’t play (12 cards).

Which cards, and why

12 cards because the rules engine has no data for it — usually a card newer than the engine’s card list:

  • Triangle Ecstasy Harpie Lady Sisters
  • Harpie & Amazoness Rakshasa Formation
  • Amazoness Spellcaster - Forbidden Spell Dance
  • Amazoness Dramatic Rescue
  • Harpie Lady - Elegant Egotist
  • Eyelluring Mirror Wall
  • Elegant Tri-Mirror
  • Amazoness Chain Master - Brink of Death Chain Dance
  • Necromancer of Dragon Magic
  • Amazoness Swordmaster
  • Amazoness Fighter - Instant Kill Dance
  • Harpie Lady - Alluring Dance

  • The 1-card side deck is not used: a playtest is game one.

Every duel is dealt from a seed, which the address keeps once you start: reloading the duel deals the same hands again.
