The game is rigged against you basically
It is easy to notice it will let you win a few games as in it purposely matches you against other people with a deck that you counter then if you win to many and they do not want you to proceed so that you will spend money to get better cards they will match you against your counters or decks that are literally not stoppable by yours because perhaps you have only 1 air defense and you could say it coincidence but it is not coincidence that you will be put against the same deck over and over and if you switch they will just start finding people with a different deck to beat you
