Hi I was thinking about a similar concept with keeping the Doubling Buffs. I use parallell universe it is pretty neat, here's my deck:
7ms 7ms 7ms 7ms 7ms 7ms 7ms 7ms 7ms 7ms 7ms 7mu 7mu 7mu 7mu 7n9 7n9 808 808 808 808 808 808 808 808 80b 80b 80b 80b 80b
Edit: Ok, after further testing with this deck, it appears that the double effect that stays on the creature you twin universe goes away the turn after the next time you use dive on the creature. So you can't keep diving the new creature unless each time you dive it you twin universe it again... But still I like it. Doesn't really work well unupped, but I'm tired of all the same old decks and wanted to experiment with this multiplication stacking... I wouldn't waste money on an upped version of this outside of trainer /sigh
