Casual Challenge is a constructed format and therefore adheres to the following constructed rules:
Minimum of 60 cards
No maximum deck size, as long as you can shuffle your deck unassisted
Up to 15 cards in your sideboard, if used
No more than 4 of any individual card in the main deck and sideboard combined
(with the exception of basic lands [snow-covered basic lands are also basic lands])
Each card that is Vintage legal can be played, as long as the deck follows these two specific Casual Challenge rules:
The sum of the value of all cards in the deck shall not exceed 25€ (this includes the sideboard)
Value is taken from the price of the cheapest vintage legal print in grade EX or higher
Since August 1st 2022 the 25€ will be represented by 2500 Budget Points (BP); 1 BP is worth 1ct
The Budget Points for each card won't change during a season, so you should check your decks once per season (roughly every two and a half months)
To check your deck for budget point cost, use the deck checker below
"If you play 40 cards that are not basic lands, your average card can cost 63BP."

The top 50 most played cards per format and season shall not be played (they are considered banned)
The formats considered for competitiveness are Standard, Pioneer, Pauper, Modern, Legacy and Vintage - so all paper tournament formats.
A current list as Google Table can be found here
MTGGOLDFISH offers those list regularly updated
All cards that are banned in any of the mentioned formats, are also considered banned in the Casual Challenge
Currently, the easiest way to check your deck for legality is to set it up as a Scryfall deck list and then use one of our homemade browser extensions.
Use Google Chrome
Install the Scryfall - Casual Challenge Checker extension
Create a Scryfall account
Create a new deck --> choose Variant and then Casual
Enter all your cards or use the "Add to Deck" button on any card you found on Scryfall
When viewing the you'll find a button "Enable checks" in the left sidebar. Click it to enable legality checks for this deck
Use Mozilla Firefox
Install the Scryfall - Casual Challenge Checker add-on
Follow the steps 3 to 6 on A
Bonus: The add-on also works in Firefox on Android, for quick checks on the go!
Pro
The extension tries to be smart. Decks that have "Casual Challenge" as part of their name are automatically checked without clicking the button. Also it remembers which deck you enabled checks for.
Tip: "CC" also works for the auto-detection
You can use all the cool features of Scryfall, like their day-precise pricing and amazing search functionality while still seeing whats legal or not for the Casual Challenge
Both extensions are actively developed, so new helpful features will come
Contra
There are decklist tools out there with way more functions, but the extension is only supported for Scryfall
Depending on your preference for card condition, card language and time of last print, prices for cards can vary a lot
It's strongly recommended to buy cards via cardmarket, a player to player marketplace with the best prices in the European area
Once you have an account, you can use the Wants feature to put in your decklist and use the Shopping Wizard to get the best combined price
Be vary of shipping cost (included in the 35-75€) and time. Certain countries are very expensive (e.g. Netherlands) or even have customs (Great Britain, Switzerland). While in other countries (especially south/east Europe) shipping can take very long (1-2 weeks is usual).
--> for the fastest shipment and lowest shipment cost you can buy everything from your country (there is a filter for that on the shopping wizard), but this will increase card prices
You can print out so called "proxies" --> cards intended for testing out decks or to get otherwise hard to acquire cards
A recommended tool is MTG Print by CARD TRADER
Make sure you set the print size in each step to 100% and check the chosen prints: arena versions of cards will look bad when printed out.
It's highly recommended to print in a copy shop with colors. This will cost you around 4€ per deck
If you are a student or have otherwise access to a shared (color) printer, you might get it even cheaper
If you print more than 1 deck, I'd recommend you using the cutting service offered by most copy shops (which usually costs around 4-8€ but for basically any amount of sheets).
We have around 40 decks already in the play group with 14 active players --> there are more than enough decks to just borrow a deck
But keep in mind that constructing and maintaining your very own deck is at least half of the fun of the format
Roughly: Average of the cheapest daily prices of legal prints since the last 4 months.
More details coming when someone is asking for them :P
