Just Started Help

[MustangCobraSVT]

I just started FFVIII having only tried playing it when i was a little younger. I started playing and i already have some questions that i couldn't find the answer to anywhere else. So i came here to all you knowlegdable, lovable people. I was trying to play the card game and i understood the jist of it. I get that the higher number will win against the lower one. I don't understand how the plus aspect of it works. The opponent has cards that are in an L shape. Now say that i put a card that has a 3 and a 4 that touches the opponent's card's 2 and 1 respectivily. They way i understood it is that beause they both add up to five that i would get both those cards, but i didn't when i played. How is it really supposed to work. I was also wondering how to get new limit breaks. Do charecters get more as they level up or do they learn them by using them alot, or is there a different way. The last question I had was in the junction menu (under the charecter's picture) it saids something like S/T-D/U and E/L-D/U. Im not sure if that exactly what it said but it was something like that. Any help would be greatly appreciated, thanks in advance. No spoilers please.
