Grinding to get Hero Alt Art

I finally got my Alt Art for my Warlock hero and I couldn't be happier.  BUT... much like other awesome things, I want more.  So I've been grinding to get my other favorite class alt art heroes and I am finding the trial to be ridiculously tough. 

SO my question comes to the forums to see what has everyone else done when you see the light at the end of the tunnel, like when you are around 950+ wins, and you start to feel like you cannot keep going?  I am trying to kill off my Rogue  wins and I have less than 15 left to go, but it honestly feels like I am getting encountered with every single possible counters to my decks.

This isn't a salt thread at all.  I get the RNG of it all.  I am just more conscious of it all right now as I just.... want... my... pirate... Valeera.  

Follow up question on that as well, has anyone felt that same way when grinding out the last wins for your alt art?

I can feel your frustration. Way back to year 2015, I was 5 wins away from my first golden hero, Hunter. I went all the way up with my own beast midrange build. From there, I couldn´t win a single game! For two days straight I couldn´t get the last wins. I got so frustrated I crafted Face hunter for the very last win and I finally did it first try. Biggest relieve :D

On the other hand, this month I just got my first 1000 win portrait too, but the last 50 wins were quite easy. I often play on both ranks, makes the grind much more faster. Maybe try Wild for the last wins? Odd Rogue is nuts. Anyway, good luck, you´ll be there soon :)
