Ok.
I've tested this deck a lot
when I say alot, I mean probably over 100 games.
I had a working list of this with DP5 japanese cards like months before we even got frosslass.
actually, there is no CORRECT way to play the list
thats whats soooo great about this list, its techable to your format.
for instance. I run
3-3 frosslass
2-2 claydol
1-1 yanmega
2-2 starmi
1-1 bronzong
1 spiritomb
1-1-1 omistar
1 mesprit
It may seem "all over the place" but in actually its not. Rosans research just grabs what you need depending on what you face.
for instance, I also run 1 lake boundary and 2-2 starmi because Magmortar is big where I live.
I like 1-1 Yanmega, it lets you spread garrentied 1 damage on EVERYTHING (unlike bronzong) to setup for bronzong, and stall a turn for your NRG attachment (so you can attach and rebuild a second frosslass) free retreat is nice too!
I used to play this without omistar.... however
I played games against Torrerra where, I had like 80 damage on like 3 pokemon and
YOU CANT TARGET LEAFEON OR TORRTERRA LV.X with devo!!!11 which STINKS! you will never spread enough to knock out those huge beasts with 10 damage at a time.
soo....
it works liek this, you search early game with Rosans research. You see whats in your deck. if you have helix fossile but no omistar (or ominte) you grab misprit, and you play that to retreave the missing 1 from the prizes.
that way 1-1-1 cant fail you to bad.
all up to you though.
