In Modern I think the RG Prowess deck is slightly behind the URx version (mostly because theres no such a card as Preordain)
Sure, your opponent can destroy this enchantment in order to undo the damage, but youll hopefully have already managed to turn the tides in your own favor by the time that they find an answer
Then you tap three, one of which is Tangle Wire, so this ends up netting you a lot of tempo if it comes down before they can find permanents to tap other than lands, especially if you have one and two drops that you can tap
The format remains fringe, but if it becomes as well-established as something like Pauper, we may see more movement on the Reserved List cards that actually see play in it like Phyrexian Dreadnaught and Gaeas Cradle , as well as staples for more budget decks like Pyroblast in Burn
