I'm Marie and I can't guarantee that this deck will work against all your opponents but you can try.  I won 3 out of 5 matches using this deck so maybe it will work for you.  I'm sending 2 variations of it so be sure to read both.  The first one is a Base and Jungle deck.  My other one... you'll see!

    Scyther is my favorite card.  Double the attack.  I don't think there's too many basics that can dish out 60 damage.  Mr. Mime's Invisible Wall is my favorite attack.  You don't get hurt!  He makes an awesome card.  Jynx is in there instead of the rare Mewtwos so you can get the deck easier instead of trading all your rares for the Haymaker Mewtwo.  If you don't happen to have any Jynx, try the Promo Mews or the Promo Mewtwo.  You can use all those in the decks.  I tried them and it worked.  Ponyta is just backup.  Its attacks are good for a basic and you can recycle it to keep it on your bench.  Jigglypuff is great.  I love it.  "Jiggggelyypuff, jiggellyyyyy-yypuff"  your opponent's asleep and open for a pounding!  And if you don't wanna pound with Jiggly switch it with something like Scyther.  So far I have 3 other variations to this deck.  I reccomend trying all of them.  Look out for them!
