Thanks to the upcoming Final Fantasy set, Magic: The Gathering is getting a fishing minigame, as well as a new kind of summon and more cards that transform

Each of Magic's crossover sets has adapted its source material to the rules of Magic: The Gathering in a different way. One of the ways the Final Fantasy set will do that is with double-faced cards that represent bosses and other characters becoming their final form. Cecil, Dark Knight becomes Cecil, Redeemed Paladin, for instance, while Garland, Knight of Cordelia becomes Chaos, the Endless, and Emet-Selch, Unsundered becomes Hades, Sorcerer of Eld.

Also, the fishing card can transform into a camping site.

It turns out that not even venerable old Magic: The Gathering is immune to the lure of the fishing minigame. Thanks to Final Fantasy 15's boy-band road trip, we'll be able to play Sidequest: Catch a Fish, a card depicting Prince Noctis demonstrating why women love him and fish fear him that lets you «fish» the top card off your deck each turn. If that card's an artifact or creature you get to keep it, and get a free food token you can use to heal. After that you flip Sidequest: Catch a Fish over to become Cooking Campsite—a land card you can tap for white mana and use to give all your creatures +1/+1 at the cost of an artifact.

The other mechanical twist revealed so far is summons. Given that summoning monsters to fight for you is the original conceit of Magic: The Gathering it's funny to see it highlighted thanks to Final Fantasy almost 32 years later, but the way summons work here is quite different to what we've seen before. Final Fantasy's summons borrow the saga mechanic, previously used for cards that have changing effects on the turns after they're played, normally used to represent a developing plot. In the Middle-earth set, for instance, the saga There and Back Again represents the story of The Hobbit and, on the third turn after it's played, lets you bring out Smaug.

Final Fantasy's summons likewise have different effects on subsequent turns and vanish once they're done, but also get to act as creature cards the entire time. Summon: Shiva uses Heavenly
