Ra Blind 2nd

Fairly simple idea. You have 12 cards in your deck that can tribute your opponent's field. At worst, you wipe them out, at best, you use ancient chant effect on GY so Ra can get the attack of all of your opponent's monsters tributed with soul crossing, and swing for a hilarious amount of damage to their stunned faces.

Remember that Soul crossing and superpoli are quick plays, so they can be set and activated at the moment of peak disruption on your opponent's turn. 

If you resolve Soul crossing right as they have 3 monsters on their field, not only YOU get sphere mode, but usually stop them dead on their tracks
