Alright, I’ll spill my Hearthstone soul to this question because I find it a fun one.
I dabbled in HS at launch, but stopped shortly after due to life priorities, and most of my hobby time went to WoW back then. Then my eyes beheld the beautiful diamond Varian card with the release of United in Stormwind, so, as someone who loves all things Wrynn, I had to have it, and back into Hearthstone I dove.
I play the heroes and decks I find the most fun, regardless of whether they are the best. I would say I lose more than I win, but that’s ok with me. I’m an adventurer and love quests so I play to complete those mainly. The wins do come, and when they do, they are all the more enjoyable.
My favorite decks are: Warrior (imagine my thrill after requesting a Varian hero skin and then seeing it in the shop, with its awesome animations and voice acting (love you, CM) to boot! ); playing against Anduin is so much fun when you play the Warrior Varian card. (Also, in a little nerdy RP thing I do, I never attack Anduin with Varian in a match, only his minions ).
I also love the gala/party Medivh skin as a Mage, Priest (Little Lion or Prince Charming Anduin), Lor’themar Hunter, and Edwin Rogue. Also, Frostmonger Sai is cool if I ever need to play a DK game.
I used to auto concede to Priests because I find someone repeatedly copying your cards annoying (and not the RP I think of when it comes to Priest) but now I just chill and roll with the punches.
As far as emotionally…that’s an interesting question because this game can definitely be live and die by the sword. There are those amazing games where the stars align and everything just goes right, or you magically draw the one card you need just at the right time, or some miracle happens and you pull off the win by the skin off your teeth. But of course it goes the other way as well; you’re moments away from certain victory, then somehow it all goes terribly wrong. Those are the ones that sting, but I remind myself how it all balances itself out in the end.
And it’s the randomness that makes it fun!
