Notes: you won't win the duel with this deck, just deal 2000 damage with Kickfire and call it a day (don't surrender, for I don't know if that counts. Just let Kaiba finish you off). If you have more Gaia Souls and/or Regretful Rebirths, replace the Generation Shifts.
Oh, and forgot to add the following things: as far as I've seen, Kaiba won't use Twister on Kickfire. Also, Kaiba will not attack a monster reborn by Regretful Rebirth (making it easier to have it be destroyed by the effect to trigger Kickfire), unless he has ANOTHER monster available for a direct attack afterwards.
