Why is this card good?
Foreboding Ruins is a solid Rakdos dual land that belongs in basically every B/R deck that isn't running a critical mass of basics. It's part of the "slow land" cycle, and the key thing to understand is that its conditional untapped entry rewards early lands and decent basic counts — reveal a Swamp or Mountain and it comes in untapped, which makes it most reliable in the first few turns.
The catch is the inverse: in the late game, when you've already played out your lands and basics, it almost always enters tapped. That's the opposite of when you want a tapped land, so it's not perfect, but in a 99-card singleton format you're rarely chaining duals turns 1-3 anyway.
Run it in any Rakdos build — aristocrats, sacrifice, spellslinger, aggressive midrange. Skip it if your manabase is heavily basic-light or you're running lots of fetches/shocks/fast lands and don't need another tapped-risk source.
