I played something similar to this, but a mono-aether with 5 Pu's, 5 Lightnings, 5 dim shields, and 15 pillars. Beat a LOT of AI5s with that. Copy their creature, then kill the original. When your opponent gets too much attack up, start chainin' dim shields. I played somebody with a rainbow dragon deck in pvp1 with this deck...at the end I had 4 dragons, and he had 1. The rainbow version I made was somewhat similar to this, but I hadn't thought of using precogs (nice twist).
I think I'll try this type of deck again sometime.
