The most effective way to win this lottery
would be to develop a working relationship
with Lucifer, who according to Gavin and Yvonne Frost,
Lucifer is considered "lord of all the wealth in the world" according to the grimorium verum.

See his livejournal for Paimon and some of the most fascinating evocation diaries I've read. Lucifer comes up but he refrains from saying what was told to him by Paimon, who is "very obedient to lucifer", according to the Goetia.
