This is my first idea mokuba action duel
it started nice and sunny day for mokuba ride his bike with his brother seto. Mokuba ask I need some more yu gi oh cards for my deck but seto say no you just prove to me you are strong enough. Mokuba say my card are weak and they aren't strong as your deck and the yugi's deck. Seto say okay I will give you more cards on one condition is to beat someone with your deck. Mokuba say it no fair for me and everybody else level higher than me. You just to find someone to duel with but this weird light open up sent to a different world. Seto say what is this strange place and it one these magic trick again. I has enough with it already and let go home but someone came to seto and say I will duel your little brother. What is your name and why you want mokuba to duel you. My name is dark mokuba and I has these cards the dark blue eyes dragon. Seto got mad and say fine I will let mokuba duel you and win for me. Okay! There are new rules to this game and mokuba just to listen these rules. But it not any regular duel but it action duel.
(I will skip those rules since everybody know the action duel rules already)
seto ask mobuka you are ready to win and mokuba say yes. I going active the field is track field and mokuba say wow neat field you got there. Thank you now let duel

Nice move you got! but not will change anything and now my move draw. I going wipe you out but first i play a spell dark wise core fusin and let me fusin two monster. I pick wise core and dark blue eye dragon from my hand to form powerful beast call dark wise core blue eye dragon ATK 3000 DEF 2500. It can attack you right now but first mobuka running for a action card find it call spell damage time and this card effect is you will take the same damage as me. dark mokuba say what. Both of them flying backward but seto want the duel to stop and mobuka say with I quit now and I will not get those new card. I going to win this thing on my next turn.

mokuba say yes I win the duel and he fall down. Seto walk up to him and we goes back to our world but dark mobuka want mokuba keep his card and serenity too. He earned it for himself and don't worry I has ten extra copies of that cards. The light thing open up to take them home. Seto put mokuba to bed and say wow you have a long way to go with this card will help mokuba be a better duelist but why he what give this card to serenity. Maybe those two will faces with the same dragon good night mokuba.
mokuba waked up on this morning to see the two card and note from seto. The note say give that one card to serenity and P.S. I left you a little gift for you. Wow new cards for me and it will be my great day. Thank you seto and your are greatest brother in the world but I will take few cards out. I will give the rest to serenity because her deck look weak. Serenity come to visit and say hi to mobuka and mokuba say hi! I will give you something to keep. So mokuba give few cards and she this card wow this card almost look like blue eye white dragon. Let goes play the game for fun.
the end!
This is the only one shot crossover hope you enjoy it.
