Gwent cards

Right so I'm at the point in the main story if I go any further I'm gonna fail the gwent quests. Never really got into it because I kept losing but I've won live 3 out of the last 6 games and makes me wanna do it to get as close to 100% as possible.

You know how in scrabble you can put your letters into a program to give you words, is there anything like that for gwent so I can have the best chance of winning
