Yes, these cards are legal in eternal formats such as Commander, Legacy, and Vintage, though they are not legal in Standard or Modern unless they were already printed in those sets
This set fits within Wizards of the Coasts block model and caters to both standard format and eternal format players
1 pack : 10 cards (total 179+30 types)
This card was inspired by the idea of a creature enchantment that overwrote everything on a card
Anyways, I've run Phantom Monster in lots of places, like Pauper online (where it's reprinted as a common a long time ago) or in Commander '95 (where you play cards printed up through 1995)
