Hello, I'm Andrewsmile the #1 ranked Challengers! arena player for 99% of the season, and I thought I'd put together a tierlist because its a question I get asked fairly consistently especially because I have some pretty controversial opinions about this game (MUA is terrible, sailor is better than UFO, etc). I stole the tier list format from Fletcheese, another great player who published a guide linked in the tier list that gives a great overview to the general strategy of the game. I tried to organize the tiers based on my drafting strategy and give clarifying notes on each card. Let me know what you think

I also thought I would take this opportunity to go a bit more in detail about a note I made in the Jester slot, because that card has a not-readily-apparent drawback that I think make it, MUA, blacksmith, and movie star significantly worse- namely the need to run independently bad cards to make it good. Because its support cards are generally bad, the jester and the newcomers work best when removed as a unit. If you cut just the newcomers or just the jesters, the other stack becomes MUCH worse and is barely worth running at all barring other support. Consider the following situation which I don't think is uncommon for many players: Going into round 4, your first foray into B deck, and your deck is as follows: 3x newcomer; 1x dog; 1x champion; 2x jester; 2x movie star; 2x gangster (perhaps you saw double movie star turn 1 but you weren't able to find makeup artist in subsequent rounds). This is a great deck on turn 3 and in the early game, so you've probably won all 3 rounds so far. However, you don't see any pairs or particularly good cards in the B deck, so you reroll, and again no duplicates. Say the 2nd hand is one each of the 5 power animals just as an example. You take a rubber duck and a horse, but what do you cut? You have too many duplicates to safely run 7 uniques, so you will need to cut 2 stacks. Cutting the dog is an easy choice, but what about the next stack? Cutting newcomers is obviously bad, because both jesters and movie stars need them. Cutting movie stars or jesters feels bad because they could both be worth 4 power each. Gangsters are similarly powerful. You probably cut your champion, but its pretty early for that and in return for 10 power you cut 7, meaning your deck got only marginally better and if you cant find duplicates next round you will probably stall out and not make the final. In a vacuum, you would easily cut newcomers here instead of champion but since you are running jester and movie star you are a bit stuck with running the newcomers which are very bad on their own. This is just one example but is indicative of a not-uncommon problem. Hopefully that makes sense, let me know if you agree with my reasoning

), and thats because they can also fail on pos 2 or 3 or even 4 as well.
