In Bolas's Clutches
Most blue theft effects stop at creatures: a mind-control aura names a creature, resolves, and hands you a body. The design here trades that narrowness for reach. The middle line lifts control of any permanent type at all, so planeswalkers, artifacts, problem enchantments, even a key land fall under the same aura, a meaningfully wider net than the usual color-pie mind-control effect casts. The third line, making the enchanted permanent legendary, is the historical curiosity: it does no removal work when you steal an opponent's permanent, because you control the stolen copy and they control their own, and the legend rule only fires when one player holds two same-named legends. That clause is aimed at your own board and at older synergies, not at executing the victim's duplicate. The honest cost is the six mana and the sorcery-speed window: it is slow to deploy and evades nothing on the way down. It also carries the standard aura liability, sliding to the graveyard for a plain one-for-one if the enchanted permanent leaves before you have gotten your use out of it. What the rate actually buys is universality: a single card that answers a category most theft spells cannot touch, with a rider that reads meaner than it plays.
