Yeah, it could work, but it'd be tricky to pull it off. I suppose it could help if you used cards that summon a group of ritual monsters, such as "Contract with the Abyss", and other cards such as "Cost Down" to lower the Ritual monster you're about to summon's level. "Fulfillment of Contract" might be helpful too, to get back your ritual monsters used as sacrifices. Also cards like "Soul Exchange", so you can tribute your opponent's monsters. Then the searching cards such as "Manju of Ten Thousand Hands". Hmm.... this is something I might find interesting when i get the game :P (Currently saving up for it ^^)
