“Stop trying to make fetch (lands) happen.”
Broadly speaking, when you play Magic: The Gathering via its digital incarnation in Arena, you choose a format to decide whether you want to play with just new cards (Standard), a mix of new and old cards (Historic), or a mix of new and old cards but none older than the popular Return to Ravnica block (Explorer). There are other formats like Brawl, which lets you add more players, or Alchemy, which includes digital-only cards, but if you want to play a traditional one-on-one game of constructed Magic in Arena just like you would at the table, those are the three formats you pick from.
Until now. With the new Timeless format, Arena has yet another way to play. “We are creating Timeless as a home for MTG Arena’s most powerful cards”, senior product manager Dave Finseth wrote on the Magic blog. “As MTG Arena has grown, we have accumulated extra strong sets like Wilds of Eldraine Enchanting Tales and Strixhaven Mystical Archive. These cards did not have a great place to be played outside of their Limited formats without overrunning an existing Constructed format.
