strategies on Pokemon cards from cory and christian useful tips for Onix : get an Alakazam. use damage swap on your strong Pokemon and put the damage counters on onix since onix has 90 hp. this works well if you have no potoins. Gastley: if your opponent puts out a strong pokemon send out gastley and have some defenders with you. when he or she does an attack use yor defenders because gastley only has 30 hp. then use destiny bond on gastley and if your opponent knocks you out you knock his strong pokemon out. weak 1 strong 2 : you would want to send out your weak pokemon first so you have your strong ones left to fight last. we are tired of the question: '' is chansey better than charizard'' . no chansey is not better than charizard
