Timeless is a new non-rotating, Constructed format where every card on MTG Arena is legal. This includes digital-only cards, the upcoming Khans of Tarkir set release, and any future set releases. Timeless will use the re-balanced versions of all digital-only cards, but the original tabletop printings of all non-digital cards.
Timeless will be the first format on MTG Arena to have a restricted list. If a card is on the restricted list, only a single copy of that card may be included in your deck and sideboard. Cards will have to earn their place on the banned and restricted list, and only those cards that have proven to be negative fun or far too powerful will be added.
The initial restricted list for Timeless includes only the following three cards:
- Channel
- Demonic Tutor
- Tibalt’s Trickery
So Arena gets its own Vintage format. I guess this is the result from the No-Ban Historic testing, will be interesting to see how it shakes out
Edit: Oh we get Timeless Dragon on Arena too! And they confirmed that fetches will be banned in Historic
