U want an under rated and potentially great cards,  i got one for ya LASS
why do i think its great?  well it kills raindance and stall.  hard to use but still a personal favorite.  I just made a dodrio deck with lass,  so heres how i use it.  I use fast PKMN like scyther or even use dodou or chansy if i dont have scyther then use my trainers fast before lassin.  if i cant use my trainers a dont waste em just try to get lass with em or let them go back in my deck.  a first turn lass can seriously mess up an opponent.  dont use lass when ur setting up something around a trainer in your hand.  Use it when u think your opponent is setting up something.  What your should do is try to get a first turn lass nomatter what they play to ruin any possible early oaking and effectively setting your self up for an early ko and win.  Let me ax u somethin how many times have u been baout to knock out lets say muk with no energy with your mewtwo and your about to absorbtion.  He has a fully pumped chansy at his bench and a full hand.you both have one prize left.  Remember this is ascenario but the ideas common.  He switches for chansy and bang he kills ya for the win.  Lass would have pervented that from happening.  that might never happen to u but something like it has happened to me.  Remember lass when making a deck.  he helps when u want to stall or in general mess the plans of your opponent
