Congratz dude! :) Hitting rank 1 Legend is not easy, even with Zoolock.
It is really sad this thread (made around 8 hours ago) has so few replies until now, considering there are many users here who usually love to congratulate people for just hitting rank 5 for the first time, something almost anyone can do. So sad... :(
Blizzard should make a special stream lessons or youtube videos in which they explain the the only way hs should be played is with supa dupa 1000 IQ control/combo homebrewed decks and 30 minutes long match is a minimum time period that proves you're not braindead blah blah something etc.
How much time did it cost you to reach that spot? (no salt, I'm just Interessed how much time you need to play to reach it)
500 games is about 75 hours with his deck. I used the approximately 3 hours for 20 games in his screenshot. that means about 2 weeks into the season he's playing around 5 to 6 hours daily every day at least.
