Ok, now most people look at the status changing effects, and say Poison is obviously the best, because it deals 10 damage at the end of every turn. And I would have to agree, poison is the best status effect... but poison is missing one thing the other 3 status changes do.... affect pokemon powers.

 

Most pokemon powers read as follows... "You may do X. You cannot do X if this pokemon is Asleep, Confused, or Paralyzed." Try confusing the opponents Blastoise, Alakazam, or any of those other decks that are based around the pokemon powers. Kind of stops those decks now, doesn't it?

 

Just something to keep in mind while building your decks.
