Charity, other than being a great Mime killer, has another great use.  The
text on the card says: "Attach Charity to your Active Pokemon.  Unless that
Pokemon is knocked out, return Charity to your hand at the end of your turn. 
If that pokemon attacks and does damage to the defending pokemon, you may
reduce that damage by any amount (rounded to the nearest 10)."  Instead of
using charity as a Mime Killer, (since no one uses mimes anymore), u can
place it in a bench destruction deck (i.e. Dark Arbok, Brock's Golbat).  If
your opponent has any benched pokemon, simply GOW for one that has at least 1
retreat cost.  Then, to ensure u dont knock out their active pokemon, you
reduce the damage done to their active, while destroying their bench turn by
turn.  Even Better -- If you add in a "Rocket's Training Gym" then it will
take them longer to retreat their active, so more damage to the bench is done.
    If that didnt persuade you, here's another great use for Charity.  Lets
say that your oppenent is using a pokemon that "counterattacks" when you
attack it, such as Rocket's Hitmonchan's Cross Counter, or Dark Gyarados's
Final Beam.  Well, if you are about to knock out either one of them, then use
Charity, so u can make it a "clean" knockout, rather than doing tons of
excess damage, which would mean a world of hurt for your active pokemon. 
Charity, however, doesnt fit into all decks, so it is pretty limited. 
Playtest it, and see what works for you.  Have Fun!
