I hope the Zane lover will never encounter this BS AI else they will rage quit...
Used my BEWD deck vs. lvl 30. Got 2 times(restart) 🔥 hand. Had to set 2 of the 3 hand Kaibamen to just survive vs. his 2100 cyber. Then as I run out of those(still drawing only endcards...) I let my field open for his 2100 to finish my 400 hp. He summon the other cyber, tribute it and the 2100 and left his field open. With no vassall left and only 1 BEWD+Summoner I had to take a 🔥 win against him for a bit of points. There was 0 reason to do this cyber tribute move to still let me win the game... It's like Kaiba has Obelisk out with empty Yami field and then say: Okay I give up the duel!
I'm not sure exactly what happened to you, but I have seen Zane special summon cyber dragon and then immediately tribute it for...another cyber dragon.
