The strategy here is simple, use your various spell and trap cards to get E"ldlich the golden lord" on the field.
Use the various "Golden Lands" cards to manipulate your opponents field by reducing his monsters attack to 0, banishing a card in their graveyard, and removing cards on their field.
use mirror force and waboku to buy yourself time if you need it.
Use super polymerization to get some of your fusion monsters out. You can frequently use your opponents monsters if possible or even use Eldlich and your golden land cards (if they are in the monster zone).
Once your opponent is below 2000 lifepoints, you can XYZ summon your "superdreadnought rail cannon" and use its effect to deal the last 2000 damage for the win.
