I can't get over how they said so many times they have more options in a digital space and probably won't do the same thing as MtG, then they actually announce that after "lots of brainstorming" they are doing exactly the same thing as MtG and are copying the name too.
Well, maybe it took them lots of brainstorming to realize what MtG is doing is the best after all.
Sure. Totally understandable. (I think it's way closer "safest", but yeah).
The way the announcement was made seemed a little disingenuous though. They could have said something a little more candid, like, "We have spent a lot of time deciding on Hearthstones preferred solution for the balance of new content with existing content. After much internal discussion and input from key members of the community, we determined that many of the more unique options had several downsides, and that many of the benefits they presented are present in Tavern Brawl. We have decided it is simplest and best for our players if we choose the traditional solution for a CCG: formats. Let me explain what that is for those who aren't familiar."
Instead of "guys, we thought really hard, and we came up with lots of original ideas and the originalest one was this really original idea for handling expansion glut, it's called Standard format, like we don't even know if anyone's done this before or anything, but like, card gets 2 years old? bonk, it's gone. You can still play every card in Wild though"
