i would suggest checking eBay and other websites to see what prices are being offered there.
they're supposed to be 20c each
yes you should then when your older sell all your cards for twice as much money as you payed
It depends what the Pokemon cards are.
U SHOULD SPEND NOT SO MUCH AND LOOK LIKE A POKEMON FREAK BUT SPEND JUST ENOUGH SO THAT IF SOMEONE TALKS 2 MUCH, JUST SHOVE IT IN THEIR MOUTHS
$15-$20 at the most.
About 6,000 English cards
Depends on which cards. :)
ten cards
Energy cards are usually included in almost every pack you get (at least the ones I get. That's a lot of packs!), so you shouldn't worry about getting energy cards as much as you should about where to get packs of Pokemon cards in general.
5-9 Pokemon cards and 9 dollars
Depends what cards you have.
Approximately 1000 dollars per deck
