Since this deck only had 34 cards in its main deck, and this arc takes place after the Battle Citty arc, I decided to finish it using cards from Seto Kaibas Battle City deck.
I chose to go with The Lord of D. and two Flutes of Summoning Dragon because he is shown having two of them in the battle city arc and this deck could benefit from it he runs a considerable amount of dragons, not just Blue Eyes, then I added Cyber Jar because... well who wouldn't? Cyber Jar is fantastic in any old school Yugioh deck and still has its niche uses today.
And the other two are just filler cards because this deck could use a few more level 4 or bellow monsters to avoid bricking.
P.S. I added XZ - Tank Cannon and YZ - Tank Dragon to the extra deck despite it not being shown in the show because he has all the fusion materials and already runs XY - Dragon Cannon so having XZ and YZjust feels right even if he's never shown to have one.
P.S. While Kaiba does use Mirror Force Dragon, but he uses it while tag dueling with Yugi and uses his mirror force, surprisingly enough Kaiba is never actually shown having mirror force in any of his decks so I'm forced to side deck it.
