Set Left / Right Score: During match press hotkey to set score. If you set your own score to a very high value you instantly won the match.
EXP: In menu click on 'Profile' and change your EXP. Please note that you must level up by the game itself in order to get player packs. Also you will not get player packs for skipped levels. I suggest you set it close before level up, then win a game (instantly by using the other cheats) and repeat until you have all player packs.
Instant Lottery: While active you instantly filled the lottery bar in a match. Please note that you must get your lottery bar to update itself (fill it by making some moves).
No Lottery For Enemy: Simple as that while active the enemy's lottery bar stays low.
Maximum Player EP: While active in menu click on 'Card collection' and all players have maximum EP/level.
Multiply XP With: While active the XP earned after a match is multiplied. You can define the multiplier on the trainer GUI, do that BEFORE trainer activation.
