Warning: This discussion has nothing to do with Victory Challenges like CG, GG, Draft etc. This is based on actual challenges, only created for daring players
With a lot of mechanics added to the game, more types of playing are now possible. So I will list the Extreme ones, and those are:
1) The Solorun playstyle
Pretty straight foward. Use only a single deck for your entire life. You are not allowed to change the cards of it at all, so be aware which Arena 1 cards you want to fill the last 2 card slots with. There are also 2 types of Soloruns, one being the Challenging one and the other being the Pacifist one. In the first one, you are not allowed to donate to clanmates, which is allowed in the second one.
2) The Speedrun playstyle
Try to go as fast as possible to 4000 trophies. You might need some gems to have a well prepared deck for that.
3) The Randomiser playstyle
You want to play random decks every time? Go ahead. This playstyle revolves around playing with random decks all the time. Those decks are chosen by a Random Deck Generator. This is also the only challenge that vanilla players can try on their own accounts without requiring to start a new one.
4) The Levelwunner playstyle
Ever wanted to be underleveled and high in trophies? Try this! The Levelwunner player has all of his cards at Level 1/3/6/9 respectively and his King Tower at Level 1 as well, and their goal is to go as high as possible. Despite being very exhiting, they impact the game so negatively. Players overlevel even harder to beat them, thus weakening other. But if you want to take the challenge, go ahead. You will ruin the fun from vanilla players though.
5) The PB0 playstyle
You though that 1v1 was neccesary to unlock new cards right? Wrong! PB0 players overlevel their cards to the extreme without playing any 1v1 matches. And when they reach Level 8, they get access to Victory Challenges which allow them to unlock more cards, thus even more cards to overlevel. Those are really strange and odd players who would easily appear in Strange but True videos.
6) The Professor Oak playstyle
This one is pretty similar to the PB0 but it has some differences. You can get trophies but you must not get promoted to a new Arena until all of your cards from the previous Arena are all maxed and have all Star Levels unlocked. After that you go up an Arena and repeat the same with new cards until you reach the last Arena where the Challenge ends.
Those are all the current challenges available and invented. If you have invented a challenge like this, post in below.
