Elemental Monster: Online Card Game

You unlock a good portion of titles by playing the single player and the fallowing information will assume you have completed it. At class 100 you should have 58 titles unlocked with the other 42 unlocking between that class and class 430. It's possible to unlock it at class 420 so at the LEAST you should be shooting for 3.8 million EXP or roughly 2,400 matches. This should be the final trophy you unlock.

Boosting this and all the other online trophies:

Either coordinating with another player in the boosting thread HERE or just by getting lucky and actually finding another random player on the dead multiplayer, at the very start if you pull out your Ethernet cable (or turning off your router if using wifi) during deck selection you will get matched up with a CPU opponent that will use a random deck.

At the end you will still get EXP and cards as long as you sign back in to the PlayStation Network before the match is over. You need a ticket in order to get matched up. Your boosting partner/random opponent will also get a CPU opponent.
