mtg set card list by magic the gathering Secret Lair Drop Series :

There was an error retrieving a chart for Pixie Queen The issue is that someone listed ten near mint copies for $200

Wizards of the Coast confirmed that Tomb of Annihilation, Dungeon of the Mad Mage and Lost Mine of Phandelver would be the only dungeon cards introduced in Adventures in the Forgotten Realms, with no current plans to add further dungeons based on D&D adventures to the card game

Jin-Gitaxias / The Great Synthesis Price: $7.97 Jin-Gitaxias is part of the newest and possibly last cycle of the five Phyrexian Praetors

I'd avoid running him in Superfriends or most generic Gruul Creature decks though

Aside from being the set that brought us The Squirrel Who Shall Not Be Named, the major change to come out of Rise of the Floodborn was the viability of Steelsong decks
