Racing Deck Builder Idea - Inspiration From Dominion, Hearthstone and RPG Games

Hey everyone, recently I've gotten really into deck building games and began thinking about adding my own flavor into the mix.

Like many other deck builders, much of my inspiration comes from Dominion, which has molded how almost all subsequent deck builders play out. After talking it over with some friends and doing a medium level of research online, I figured that having a racing deck building game would offer its own fresh experience.
(I found salmon run to be the closest and after looking into it many people conclude that it has deck builder elements, but in its truest form is not a base deck builder.)

I have also been playing a lot of Hearthstone recently and thought it would be especially cool if in my deck builder players could choose between playing as various classes to offer access to a specific set of cards, with their own unique play-style.

So enough backstory, let's get into the meat of my idea.

I want to make a deck builder where players use cards to race to the end of a track, while providing each player with a unique play-style from each other player. I also want to promote deck diversity. By this I mean that I don't want players to just be able to by 1 or 2 cards over and over again and be able to win. I want them to be encouraged by meaningful choices to buy into a diverse deck of cards.

My deck builder would consist of 3 basic uses for cards.
-Movement, that would progress the player closer to the goal line
-Currency, like most all deck builders players use these cards to buy new ones
-Damage, these will allow players to fight various monsters that appear along their path

In addition to these basic uses, cards will also give players access to other actions similarly to Dominion.
-Draw Cards
-Gain more Actions
-More Buys
-More Buying power
-And various ways to 'play' with their decks

As I've said before, I would like to give each player access to unique 'class' cards. At the beginning of the game players would be randomly assigned or choose a class to play as. These classes would be inspired by the commonly used RPG classes.

I will give a brief summary of the ones I've thought of that I'd like to include.

-Ranger, Uses their wits to control what card will appear in his deck and hand. Places themselves in just the right spot to be able to take advantage of their ranged weaponry.

-Warrior, A slow but hulking soldier prepared for any battle. Has access to big damage cards and is able to take a beating.

-Rouge, The trickster of the group. Likes to sabotage other player's decks. Not a very hard hitter when it comes to straight up fighting but will use stealth to their advantage.

-Mage, A versatile spellslinger that is the renaissance man. Good at doing a little bit of everything but not particularly excellent at anything either.

-Warlock, Has access to powerful card, but at a cost. Will bring harm to themselves and their deck to be able to do so.

Thank you for taking the time to read this. Would love to know if anything like this has already been done or attempted. Let me know what parts sound good, bad, and which may need a bit more explanation (as i know i can just sort of fly by major details).

Thanks again and am really looking forward to your input!
