someone hacked the game.

first of all,  i always made fun of the idea " this game is hacked " and i always said that it's nonsense 

but now i'm sure 100% it can be hacked

when this season restarted, i was still 30,  my second match was against a 36 rank professor brainstorm player 

i only thought of " that guy must be soooo good to be here after only a couple of hours 

the match started, he got a quickdraw con man at the first play, then played another 2 in the second turn

and in the third he played the fourth and then a regifting zombie once and the the other and he won so fast, i only thought that he was just super lucky to have only these cards at the draw

15 minutes ago i faced him again and he was 47, the exact same play, i was so lucky that i was playing a solar flare healing deck

i fixed the situation quickly and in turn 5 all of his 4 quick draw con men were dead, and three regifting zombies

THEN

at turn six.. he played another 3 quickdraw con men and a regifting zombie

we all know that you can't have more than 4 copies of one card.. he had 7 !!!

i won the game, but i can't understand anything about what happened 

if this isn't hacking, what is it supposed to be ?!! this is so strange !
