Summon drytron monsters, search for "drytron alpha" with your spell cards, then search for "Benten" and tribute it with a drytron effect to search for "The world".
Then summon a Link-2 monster ("Cross-sheep" if you can ritual summon), summon "Linkross" and summon 2 Tokens, and finally tribute summon "The world" and I hope you have good chance and get heads. If not, try to summon xyz rank 1 monsters, and/or apollousa.
Enjoy ^^
