Which of my deck choice compromises the least?

I am looking to take part in SCG Philly and I am looking to choose between 3 "almost good enough" decks. In no particular order they are:

Storm - I don't have a volcanic island. I have all the other cards (including 2 underground and a tropical) Merfolk - No Cavern of souls and only 2 TNN Esper Deathblade - Limited to 2 Underground and 2 Tundra. I also only have JtMS.

I have all the fetches I would need. My goal is probably to minimize the feeling that I am giving up games based on my deck choice. Things like "Would the two life from Steam Vents ruin games?" or "Merfolk against miracles is that much worse without Cavern."

Beyond that, is one deck just that much better positioned in a meta as large as SCG to outweigh these drawbacks?
