i have found a great card strategy. this works if you have a Mr. Mime as
your active pokemon and on your bench you have an Alakazam and a Chansey
(or someone else with high HP).

whenever damage is done to Mr. Mime, use Alakazam's pokemon power to move
the damage to Chansey. if Mr. Mime becomes asleep, confused, or paralyzed
his pokemon power stops working though. so retreat him or use a switch or
a full heal. if you switch him, the bring out someone who has a low (or
no) retreat cost, then bring them back and use Mr. Mime again in the same
turn (you can retreat your active pokemon as many times as you want in
one turn). if you have more than one Chansey on your bench then they
could be holding from 110 damage up to 440 damage (can't have more than
four of one pokemon in a deck). you can then use a pokemon center to
remove all damage, or use a combination of potions and super potions to
remove some damage, and scoop up and return them to your hand the play
them out again with no damage.
