Wizards of the Coast recently revealed a Magic: The Gathering card from Throne of Eldraine called "Seven Dwarves" and it lets you have up to seven copies of this card in the deck, breaking the four copies limit. "Seven Dwarves" also gets a power/toughness boost for each other copy of "Seven Dwarves" you control, so the more copies in play, the bigger they are. However, in Limited formats, you can usually run as many copies of the same card in your Draft or Sealed deck as long as you get them from the booster packs but according to MTG Rules Manager Ellie Shiffrin, the same limit applies in Limited formats.
Over on Twitter, Shiffrin clarified the limit rule for "Seven Dwarves" in Limited formats, saying that you can run more than seven copies of this card in the main deck.
I was going to wait until seven people had asked, but nah. In Limited, if you're so outrageously fortunate to draft eight Seven Dwarves, you can still only put seven in your main deck. #WotCStaff— Eli Shiffrin (@EliShffrn) September 11, 2019
"I was going to wait until seven people had asked, but nah," Shiffrin said. "In Limited, if you're so outrageously fortunate to draft eight Seven Dwarves, you can still only put seven in your main deck."
The rarity of "Seven Dwarves" is common so it's possible to get more than seven copies of this card, and the deck would be so strong if you have multiple copies of this card because each of these creatures will boost each other, so I think it's just right that they put the same limit for Limited formats.
