Its dramatic and imposing, with a painterly art style
Something like Charred Foyer // Warped Space may not be at its best in this deck (as much as I want to, I wont talk about how well thisd fit in a Prosper, Tome-Bound EDH deck), but if you manage to unlock both doors, you essentially have a nice engine that works by itself
This type of details in cards are extremely cool
is definitely the more complex of the two (and perhaps is the most complex TCG right now)
It involves copying your creatures and using energy counters to let them stick around (or, in some cases, letting them die to take advantage of death triggers)
TCW worked with Pokmon Corp "to successfully retrieve and return the cards", presumably by setting up a sting though this is not elaborated upon, and says the haul "was the largest return of stolen property to date" in the Pokmon TCG
