The Ninjutsu decks it enables are more likely to be Standard ones, but I dont think that makes the card unplayable in EDH
Mystifying Maze [Wizard deck]: Very disruptive
If you dont need the aggression, Jeskai gives you a backup plan that draws a card whenever your creatures hit a player, keeping the gas flowing while you keep turning sideways
On the other hand, if you're running Creatures, you suddenly have a very powerful value engine
Make sure your cards don't get torn, bent, wet or discolored for maximum worth
There are proactive plays here, too, with Shivan Dragon and Braingeyser letting you pull ahead when the window presents itself
