I could offer all sorts of excuses of why I didn't post this card yesterday when I should have. I will not do that. Instead, I offer you scour. This isn't the way the mechanic is usually worded, though.

That's the bunny. The wording is not the best thing in the world (it's all 'card', 'card', 'card'), but I couldn't figure out how to improve that.
Here's how it is supposed to work. You play Ritual of Petals, targeting a creature in your graveyard. Scour triggers, putting another effect (the scour effect) on the stack on top of Ritual of Petals. Scour resolves first, independently of the spell (so the spell could be countered and scour would still resolve). When scour resolves, you reveal the top X (in this case 4) cards of your library. You may take a sorcery (since Ritual of Petals is a sorcery) from those cards and put it into your hand. Put all remaining revealed cards on the bottom of your library in any order. If you revealed no sorceries, you don't get anything. If you revealed multiple sorceries, you only get one (although you don't
have to take any of them).
Land Bridge works in much the same way, although I'm not sure if it's legit because I don't think lands go on the stack. Regardless, when the scour ability resolves, you reveal the top card of your library. If it's a land, you may put it into your hand. If you don't, or it's not a land, put that sucka' on the bottom of your library.
Scour is a triggered ability.
