I got 4 blue eyes and whole exodia =) i dont know how to just duel more

Beat Yugi 5 times in a row in the match duel and and beat him 7 times in the single duel.
And then import your whole deck and then beat yugi 1 time in both duel modes. After that
export your deck and then beat yugi 4 times in match mode then the screen says "save duel
as replay data" press NO then it says "you won 5 limited cards for doing this cheat. Then
go to deck construction and take out the following cards:Silver fang,Mammoth graveyard,
Mystic clown,Armaill and metal dragon. Now your 5 peices is not in your folder, you must
intstantly beat yugi by having your life points 4000 or more than u will find the 5 peices
will be in your folder. Take them out and Beat Yugi in single mode one last time to use
the 5 peices. Thank

Get at lest 2 mystical sheep and kajezin and also monster reborn. Then summon kajezin and
wait till he summons BEWD and when he attack kajezin uses kajezin effect against his BEWD
that is make its attack into 0 and it will be destroy. Then use monster reborn and wait
till you get polymezeration and 2 mystical sheep.D on't summon it but activate
polymeziration and ta da, you get to use BEUD.

and i dont know
