I saw the most “fun” in players face when we saw a ton of different decks.
But new and fun is often not good enough for ladder.
So at the end only a handfull decks make it to the best to be able to ladder up which leads to a fast boring gameplay of the same experience.
Is ther any chance to have more then just a handfull strong decks? I mean like hundreds of decks that still can ladder?
What must a game mode have to allow alot of deck-variance and grindability?
No. People simply don’t work that way. Consider your local supermarket/grocery store for a second. How many types of cookies are there? Dozens, if not literally a hundred. If we broke down all cookie purchases, would we see that type of diversity? No; the vast majority of people buy Oreos and Chips Ahoy. Even if we had literally one thousand viable archetypes, there is no means whatsoever to take a mass of thousands of people and prevent them from narrowing what is technically a huge variety of choice down to a handful of popular meme choices. We wouldn’t even know there would be a thousand; once we got to a couple dozen known viable archetypes, we’d lose incentive to keep searching. That’s not even game design; it’s human nature.
Fun is correlated to actually improve yourself.
The more you improve yourself the more you get your eyes open enough on how you deal with the world around you and identify oportunities for New ways of doing so.
Creating Variety as consequence.
The way to be able to have a experience that is above average is to do effort to be above the average.
Any ladder system with rewards will naturally have players gravitate towards whatever wins more. The only way you can make a “ladder with variety” experience is by not allowing players to build their own decks.
If players can build their own decks and there’s something at stake, the majority will gravitate towards the best decks they can build with their collection.
First, I think you have a loaded premise, that there’s only a handful of good decks available. We actually had twice as many before the mini set, which ironically shrank it down to 6.
Hundreds, yes. It would require Blizzard undergoing a massive balancing project in the Wild format. When I say massive, I mean that it would take a year minimum, with a lot of personnel dedicated to play testing nerfs and bans.
The card pool in Standard is insufficient for hundreds (note your s making it plural and therefore requiring a minimum of 200 decks to achieve success). For Standard to say get to 35 Tier 2+ decks, first we would have to assume a 6 expansion meta. Then we would have to assume 3 weak expansions are released in succession, and expansions from the previous year are nerfed to meet the power level of the new expansions, over the course of a full year. And those nerfs would be happening at an even more frequent rate than we see nowadays.
Are you trying to say that Oreos are a meme?! 
yes

the single most important thing is card/deck balance. the second most important thing is that “those” type of people don’t all play the most broken OP deck which breaks the game. the second thing is likely to not change since “those” type of people seem to continue existing. so our only hope for more fun playing ladder is that blizzard starts doing a better job with balancing new cards. they’re doing a good job already with nerfs and fixes but it needs to happen even faster bc “those” type of people exist. i’m assuming given the nature of your question that you play ladder competitively. i only play ladder and i only play the game for fun. the ladder has the best matchmaking so that’s where i play. i’m looking for games with people who aren’t playing broken OP decks or meta decks. i’m happy if i’m playing against people at any rating so long as most of my games are not against those broken and OP decks. the soul of hearthstone is creating decks and playing them and that’s the only way to play for me. i’ve been doing this since the game was released.
