He does make your horses tanky while nerfing everyone else though, so I've had a lot of good luck trying him out
Some of Jace's competition, on the other hand, has been more long-lastingespecially Emrakul, the Aeons Torn, which, a full 15 years after it was first released, is still the biggest, baddest, most broken creature that Magic has ever produced, as a 15/15 flyer that annihilates your opponent's board when it attacks and gives you an extra turn when you cast it
But the themes are there
This Esper enchantment creature is an incredibly potent package, representing an infinite mana outlet, the ability to serve as a static Underworld Breach for enchantments while in play, and best of all can be built a half dozen different ways, meaning that youre never quite sure what kind of deck youre facing down at your cEDH tables
The attachment only ends if something explicitly unattaches the Equipment or attaches it to another permanent (such as from you activating the shackle ability again)
It provides mana and card advantage, making its serialized version a proper chase card with listings at $1,000
