Revealed the day of the next update on the Banned and Restricted list
Next banned and restricted announcement: Next week!
In one week from this message on March 9th, there will be a Banned & Restricted list update. Mark your calendars! As previously announced, we plan to give advanced warning of any B&R updates going forward.— Magic: The Gathering (@wizards_magic) March 2, 2020
PIONEERDig Through Time is the basis of the Dimir Inverter deck on Pioneer. The deck has a high representation in the metagame and the card has already been banned in other formats.
MODERNThe format is stable, but Once Upon a Time does exactly what Wizards is looking to end up in the format: zero-cost magic. The card is strong and appears in dozens of maindecks in a high percentage of the metagame. A ban on the card would affect dozens of decks that have been extracting value from it, like Titan's new decks.
LEGACYUnderworld Breach is the basis of this new Legacy deck, reaching Tier 1 in a very short time.
PAUPERPauper is in a good situation, similar to Modern. The only card standing out at the moment is Mystic Santuary. A ban on it would diminish the presence of Delver's decks in the format.
STANDARDEmbercleave brings speed to red decks in a scary way. Hardly Wizards of the Coast will touch Standard, but if it does, I imagine this is the card. What do you expect for this next B&R?
