I know... too many pokemon. But I need help to decide what to replace and with what. And some of these cards are "out-of-date" (in my opinion). This deck, as with all of my decks, are only made to play against my bro/friends. I do NOT play in official tournaments, so that's why there are so many pokemon, in case you're wondering.

ok cant have more then 5 of a card in and i dont think solid rage is a card

Solid Rage is an EX series card. 20 more damage to the pokemon's attacks (excluding pokemon Ex). It's not reprinted to my knowledge.

Okay now next is going to be a long one, so if you're pressed for time or don't like the wall of text, just skip down to TLDR.

The problem with the pokemon isn't *exactly* the number of cards, but you got a lot of different evolution chains and few of them have more than one in their chains. Makes it easy to get prize card screwed if you run that too often. I'm not an expert on grass/psy, but even I know that you should probably ditch Beldum/Metang. You have no Metagross (though there is a psychic one that was released in HG/SS released), or if you're not going to get involved into tournaments or anything else demanding modified legal any time soon, there's also a couple psychic Metagross there.

Really though I'd abandon at least 3 of your lines. Venusaur is one I'd definitely get rid of. If you don't run a Metagross, then ditch the...Metang line. Should get a Gardevior for Ralts, rock two Ralts actually, 2 Kirila as well probably. Shaymin's only really worth it with it's level X.

Energy Search is a useful low tier card, but it's still low tier. Rosanne's Research, although it's a Supporter, can let you search your deck for 2 basic energies, 2 basic pokemon, or one of each. It also takes up less space in your deck, and long term, you get a good deal more. Replace both energies searches with those when you can. You can ditch the quick ball and great ball for the same reason.

Another nice supporter is Bebe's Search. Put one card back in your deck in exchange for any pokemon you like. Really speeds up the setup. Luxury Ball is similar, only you don't get rid of a card, and you can't get level X with it. And you can't use it if you have a Luxury Ball in the discard pile. Master Ball isn't legal and it kinda sucks anyway, I'd trade that for the Luxury Ball if it were me.

Lastly, you can probably afford to cut the energy down a little, at least if you rock 3 Rosanne's Research cards. 17 at the most, 15 when you get comfortable. Use the extra card spaces you have for the third Rosanne and another Bebe or two. I doubt you need that many potions either, since certain Tropius can heal.

TLDR

2-2-1 Gardevior
2-1 Shaymin Lvl X
2-2 Exeggutor
2-2-1 Dusknoir
1-1 Claydol
2 Tropius (which ones btw? HS and Platinum seem useful for different reasons though)

-3 Potions (at least)
- Great Ball, Master Ball, Quick Ball
+3 Rosanne's Research
+2 (preferably 3) Bebe's Search
-1 Grass Energy
-2 Psychic Energy

Something like that, someone more grass/psychic savvy can probably be of more help. Azelf and another Claydol can always be handy, though neither comes cheap if money's an issue. On another note, Unown X, most Unown, are fairly useless. Only ones really worth using are Unown G with Guard, Unown Q "might" be useful for lower retreat cost, and Unown E "Might" be useful for the 10 extra HP if you don't want to sacrifice a second prize card with Expert Belt.

Last but not least, I'd politely ask you to organize your pokemon by their evolution chains. Otherwise it gets tricky finding all the respective pokemon, and how many of them there are.
