Leonin Relic-Warder

The thing to understand about this Cat Cleric is that the exile is leashed, not permanent. Most white answers to artifacts and enchantments either destroyed the thing outright or shuffled it away for good; here the exiled permanent is tethered to the body, and the moment that body dies, bounces, or blinks, the artifact or enchantment snaps right back to its owner. That tether is the whole strategic axis. As a clock with built-in disruption it is honest enough: a 2/2 that taxes the opponent's best artifact or enchantment while it lives. But the leash points the other way just as cleanly. Exile your own permanent and you have a sacrifice-fodder body that returns the card on death, a reusable reset for enters-the-battlefield artifacts and enchantments that you can fire again and again. The wording also creates a tidy trap for the controller: the return trigger fires on leaving the battlefield by any means, so killing the Warder simply hands the opponent their artifact back, and the player who exiled it has to weigh whether the disruption is worth surrendering later. It is removal that you rent rather than own, which makes it less a clean answer than a piece of a loop. The loop, not the leash, is what the design is built around: the two triggers fold into each other, and every blink or sacrifice outlet turns the static disruption into something repeatable.
