Look them up on yugioh wiki if ur confused about effs.

I think I'll give it a shot. Ok, so:
Tribute "Lord of D." and BEWD to summon BEWD from your hand, use "Generation shift" destroying BEWD and getting one from your deck, next use "Pot of Greed" to draw the last 2 cards.
Then, "Dark Factory" to recover the BEWD's from the grave and chain "A Rival Appears" choosing "Gyroid" and summon "Kaibaman". Activate "Lightning Vortex" discarding "Burst Stream" and destroy your opp. monsters.
Use "Polymerization" to summon BEUD, then "Monster Reincarnation" discarding "The warrior Returning", choose a BEWD and tribute "Kaibaman" to spec. summon it and "Monster Reborn" to summon a second one.
Activate "Call of the Haunted" to get the last BEWD on your field and "Aqua Chorus" to make all 3 have 3500 atk.
Finally, attack with your 3 BEWD, BEUD and Koumori Dragon for 16500 of damage and game, so you still have 1100 LP left after "Toll" eff.

Uff, so that's my solution, please tell me if it's correct.

A second solution would be: End your turn, your opp. decks out and you win

i think u got it but theres still another way
