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.

Plays under Master Rule 1 (2010 text for errata'd cards) · 7 cards play their Edison text · Side Deck not usedRules and credits

Edison is played under Master Rule 1 (2010 text for errata'd cards): every card works as it is ruled today, so this is close to Edison play, not exact.

  • The 15-card side deck is not used: a playtest is game one.

This deck: Edison card text

Plays its Edison text (7 cards):

  • Light and Darkness Dragon — Negates every Spell/Trap activation and every monster effect activation, each costing 500 ATK/DEF, several in one chain included.
  • Swap Frog — Each Swap Frog can bounce a monster once per turn even after the extra Normal Summon was gained; you still gain only one.
  • Brain Control — Takes any face-up monster the opponent controls, Synchro, Fusion and Special-Summon-only monsters included.
  • Soul Exchange — You may Tribute the selected monster this turn as if you controlled it; you don't have to.
  • Brionac, Dragon of the Ice Barrier — Discard any number of cards to return that many cards on the field, on either side, to the hand. No once-per-turn limit.
  • Armory Arm — The damage is the ATK the destroyed monster had on the field, boosts included, even if it has left the GY by then.
  • Goyo Guardian — 1 Tuner of any Attribute + 1 or more non-Tuner monsters.

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

Rules engine: YGOPro core (MIT), via koishipro-core.js 1.5.5. Card behaviour: YGOPro card scripts @ b83db1cc3f (GPL-2.0). Deckhand fixes 10 of them in every duel: utility.lua, which every card script shares, The Dragon that Devours the Dogma, Black Dragon Ninja, Branded Beast, procedure.lua, which every card script shares, Elemental HERO Tempest, Portable Battery Pack, Tri-Brigade Revolt, Tri-Brigade Arms Bucephalus II and Remove Brainwashing (GPL-2.0, derived from them: the fixes). In Edison duels, 20 cards play their period text through Deckhand’s own versions of their scripts (GPL-2.0, derived from those scripts: the Edison overrides).
