Pinnacle Emissary looks fun for any artifact deck thats trying to win through either combat damage or sheer material
Jafar, Striking Illusionist If amethyst wasnt already powerful enough theres a terrifying new synergy built into their colours with the release of Into The Inklands
Once you reach the phase of the game where you can afford to do multiple things per turn, you need card draw to ensure you keep having things to do (Circle of Power, Fight On!, Travel the Overworld) or at least cards which can be used multiple times (flashback spells, Ring of the Lucii, Shambling Cieth, Relentless X-ATM092)
You'll also get a bunch of packs for your trouble
Still, its cool to see how a franchise many people love was handled in MTG form, and it gives me hope that future sets like Avatar: The Last Airbender might actually hold my attention (no Commander decks for Spider-Man !)
