Wizards of the Coast has announced that all of the cards in the upcoming Jumpstart product will be added to Magic: The Gathering Arena. Additionally, the company revealed that any of those cards that aren't already a part of the game's Historic mode will be added to the format's card pool. This is a huge influx of new cards to the online game's only "eternal" format, both in terms of reprints of cards from outside Arena in addition to new cards created just for Jumpstart.Nearly 3000 cards are legal to play in Historic, which features every currently- and previously-legal Standard set on Arena in addition to three "Historic Anthologies," 25-card curated collections added to Arena specifically for Historic. While some portion of the nearly-five hundred reprints that make up Jumpstart will likely already be a part of Historic, the set will represent the largest single injection of cards into the format since its inception.RELATED: Magic: The Gathering Officially Bans Racist Cards

However, twenty of these cards will not be added into the format as they are too powerful for the Historic environment and will instead have other cards swapped in in their place. While only a fraction of the cards which will not be part of Historic have been announced, the current list includes powerful cards like Reanimate -- a one-mana spell that brings back any creature from either player's graveyard, and is far more powerful than the Historic cards which currently accomplish the same function.
