Only with gold.
Because I have been so dissatisfied with Standard, I have not spent any money to support the mode for several years.
I mostly play Arena these days when the meta is fun or I casually play BGs when they do not suck (as they do now).
I am basically waiting for the devs to fix Standard before I will support Hearthstone again.
I hate to admit that I am actually enjoying Arena right now, despite how poorly balanced it currently is.
Death Knight has been a lot of fun to play in Arena, and I am sure that it’s currently overpowered-brokenness has a lot to do with that.
Right now, there are more than a few broken cards in Arena that are way too impactful, such as:
Astalor
The Scourge (DK)
Lord Marrowgar (DK)
Lor’themar
Soulstealer (DK)
Notice that three of the above cards are DK cards, a class which also has some other very strong cards like:
Necrotic Mortician (*)
Army of the Dead
Battlefield Necromancer
Blightfang
Patchwerk
Deathbringer Saurfang
Frostmourne
(*) Necrotic Mortician is so powerful because it’s possible to discover cards like The Scourge, Lord Marrowgar, Battlefield Necromancer, or Blightfang from it.
I have had a lot of DK drafts over the past two weeks get 6-9 wins. I currently have one unfinished DK run that is 9-1 so far.
Some other very impactful cards in Arena right now are:
Ysera
Sneed
Kalecgos
Overlord Drakaru
There is a lot of removal in the meta, which is something that I like.
Overall, I like Arena right now because drafting decks makes Arena feel less stale and repetitive to play than other modes.
