MBD strats:

Get the 14810 deck and win a card with > 900 atk or > 900 def. Take Monster Eye out of your deck and put the won card in there. Now save, exit, and we're going to try for MBDs. There are two promising opening hands.

Beast Fangs / Hoshiningen / Kami / Yamatano / Rainbow Flower (this is 638 or 640, read 640)
Beast Fangs / Griggle / Kami / Yamatano / Rainbow Flower (this is 642)

640: dump Hosh and with the last three fuse THTD, put it in Pluto and end. If he plays a Jupiter in defense it's 640 and you've got it; if he plays TriHard Dragon it's 638 and you reset.

Next turn, fuse a THTD with three cards and put it in Moon. 3d battle with the Pluto to kill his card and attack directly with Moon.

Next turn, set Beast Fangs and repeat the above.

Final turn, play Madjinn Gunn face up, do a 3d battle with the Moon THTD, then try to equip BF onto Madjinn Gunn (it fails), then kill with THTD. You get an A Pow and MBD.

642: Fuse a three card THTD and put it in Pluto and end.

Next turn, fuse a three card THTD and put it in Moon. 3d battle with the Pluto then attack directly with Moon.

Next turn, set Beast Fangs and repeat the above.

Final turn, play Madjinn Gunn face up, do a 3d battle with the Moon THTD, then try to equip BF onto Madjinn Gunn (it fails), then kill with THTD. You get an S Pow and MBD.
