I don't like bouncelands very much because they require bouncing lands, which does not interact very well with Fertile Ground, not to mention being a one-way ticket for being Time-Walked, since you play one of those, bounce a land back (perhaps even a shockland, and btw, you're missing Yavimaya's Coast in there, and possible Flooded Grove), and then get blown up or stolen, and you've just lost huge tempo in a deck that is trying to speed up its big plays. I'd go for Simic Signets isntead, although I like Lotus Bloom better.
