Cool Card Design of the Day
7/29/2016 - Stensia Innkeeper got me thinking about modern red land destruction. Here's another take.
Each turn, your opponent can choose to accept that they're down a land, or they can take 2 damage. Getting to decide each turn makes Stone Reign far less disruptive than Stone Rain, but all that damage could add up quick, especially against an aggressive red deck.
Here's the rare version, which guarantees your opponent can't save their mana by Naturalize-ing your enchantment. It's also a good demonstration of the design principle that more is not better. The point of Stone Reign isn't to force mana denial on your opponent, and so this clause defeats the design's virtue.
