I've tried everything I can think of, sableye's foresight, and slakoth's yawn, but abra always goes first and teleports away, how do I capture abra?

How far are you in the game and which Pokemon do you have with you?

Here's what I did. It's pretty simple. Use a quick claw and a reliable Paralizing Pokemon. Then hope that Paralysis holds out long enough for you to weaken it. When I used a nest ball the battle ended quickly after the paralysis because he was like... 5 levels weaker.

Try that.

I ended up hurling a great ball and it captured him instantly. Now, he's a kadabra, and I am eager to turn him into an alakazam, but I don't think I know anyone else with emerald for gameboy advance, oh well.

I'd just sweep the leg.

I've got those, I just have been spending all my time on emerald trying to level my guys up.

on diamond and pearl, can you trade wirelessly?

Yes, for those who have it, we have been all either been trading or challenging each other online.

cool, how do you trade on diamond/pearl? I want to trade kadabra so he can turn into alakazam as soon as I learn some more attacks.

You might as well import that Kadabra to your Diamond/Pearl game right away since Kadabra and Alakazaam both learn the same level up moves at the same level, and Alakazaam does have better stats. The only reason to train in the past games would to get some of the exclusive moves such as the elemental punches to be taught to certain Pokemons.
