Unrealistic randomisation with too many energy cards on starting hand

I have 13 grass energy cards in my deck and then I got these two happen in two play

1st play I got 1 Lillie plus 7 energy

2nd play I got 1 Bulbasaur, 1 meowth and 5 energy

Too often I get too many energy on starting hand which is unrealistic at all. Please do investigate if this is a bug.

Also I was unable to upload screenshot from phone with an error says Permission Problem in this website
