I think i'm gonna go with 0 or 1 Happiny in my Bliss deck.
You don't use the power that often, if you use it at all.
And the deck needs 18-20 Energies. I play 20, but _might_ take out two.
Anyways, this is sadly a very bad list. 4 Scott? That's just :nonono:
2 (TWO) Draw cards? :nonono:
Castaway, but no tools?????? :nonono: :nonono: :nonono:
Heracross????? :nonono:
4 (FOUR!) Night Maintenance????????? You only need one.
NO DELCATTY EX???????????????????????????
3 Celio's should be enough with the draw fom Delcatty.
You also might consider playin 3-3-1 Delcatty/ex, to make 1 more space. Skitty starts are bad, and you really only need 1 Delcatty in play IMO.
It needs some adustments on the energies too.
