Many people do not like the idea of a Sneasel Deck. 
They think there hard to 
use and risky.  But if I were you I would try it out because I go to a
weekly 
tourny and I haven't lost yet.(hint: it doesn't matter if you half to cut 
your deck in half just to get out a Darkness Energy or a Wigglytuff or 
anything.  You should be almost decked about 2 thirds of the way into the 
game (if you haven't won already) and you should probably have about 4 prizes 
left.  But this a comeback deck so DON'T GIVE UP you should win in the end
(USE YOUR CHALLENGES).  One more thing.  The one and only reason I
have 
Electrode's in is to BUZZAP.  It can count as two Darkness Energies. 
Oh yeah 
Unknown N makes it so that Chansey only does 50 damage to itself and any 
other attack done to you is reduced by 30.)
