rare overpower cards Tcg: Edgar Rice Burroughs and the World Legends: Booster Display – Gamers Guild AZ OverPower - Wikipedia

However, because of their distribution and the way the hobby perceived them at the time, these cards have long been considered XRCs

Compare that to Dragon Vault at 21 cards and its not hard to see why the number of cards available is growing quicker and quicker

(I should also mention that this doesn't include reprints, so fetch lands are counted as Zendikar cards, not Modern Horizons 2 cards, so they aren't skewing the data.) While Modern Horizons sets add a lot of interesting new cards to the Modern format, at this point, it's clear that they also add a lot of expensive cards into the Modern format, which in turn ends up increasing the cost of playing the format

I don't feel confident about other formats - but Gisela will certainly find a competitive home in Standard

So why cant it see play here

The sweet spot for serious collectors
