The only thing that comes remotely close to that level of power is Axe, and it doesn't work if your opponent has a Site.
Incorrect, there is actually something far more powerful:
Type: Hero Enh. • Brigade: Green • Ability: 2 / 1 • Class: None • Special Ability: If Isaiah or an Assyrian is in play, discard an opponent's character in battle, or negate and discard a single color Site, Artifact, or evil card in a territory.
You can hit Sites, Artifacts, and evil Fortresses at will with the recursion and HT, and you can also use it as a proper battle-winner. More versatile, can actually be recurred every turn, has more function, and can still do whatever it wants pre-block.
