The first 5 years of HS you could have fun with homebrews in Wild and still reach Diamond 5 (Rank 5) with ease. But over the last 1.5-2 years the powerlevel of metadecks in wild has gotten so high, that this no longer is true. You can still play homebrews, i still exclusivly play my own homebrews because that is MY way of having fun. I can still get to Diamond 5, but you have a lot less options that are viable these days. That is just a fact that you have to face, things have changed, it's not the same game it used to be.
But onceupop, why do you expect yourself to reach Dia5?
"you have a lot less options that are viable these days" -- isn't that a big pity, that you restrict urself to the decks that are viable as opposed to playing what u would like most?
You might only reach Dia10, or Gold, or Silver even but you would plausibly have more fun?
