The reason for no 4th Wasteland is because of Library, I could take out Library, yes, but it is great and can draw so many cards. And draws thier wastelands away from your volcanics.
I honestly would cut Library for 1 Island because you'll need it when under Blood Moon with 4 Mountains in play and 2 Islands, and it cuts you down to play 1 spell per 2 turns(yours and theirs). It happened to me 2 or three times in that one tournament, and I know that drawing another Mountain(Library) wouldn't have helped at all.
You could try running Brainstorms and adding some Shoreline Rangers for extra shuffling. Because I also had trouble killing people after having pitched my first Morphling, and Ranger adds another win condition to the deck. On top of that it fetches basic island if yo have a Blood Moon in play.
The reason for a lack of Brainstorm is because with Phids as your only draw you always draw a fresh card, not put in hand what you just put on top(assumably at their EoT). After the tournament, I was considering Shoreline Ranger, however a 3/4 flyer falls miserably to a 4/5 flier with a better ability. At least with Morphling you can beat it out. I know you could just as well play both, however there's really no room for them right now.
What if I were to cut the Kegs for 3 Wishes as stated before, and cut the Library and Capsize for 2 Scepters? I do like the idea of Scepter, and is great with Fire/Ice because it can be used every turn. With Wish and Rack and Ruin in the SB, I wouldn't have to worry about Null Rod as much.
Cutting 3 removal spells for three Wishes is a horrible idea, IMO. Regardless of how slow Keg may be it still gets the job done. By cutting one mana source and an emergency removal spell for 2 Scepters is...pretty much the worst idea ever because you're losing a source that you would need if under a Null Rod, replacing it and something that can get rid of Null Rod with 2 cards that lose to it.
Also, what do you think of me taking out 1 Mana Leak and putting in the 3rd Blood Moon, I need something to come out for it, and the only other thing I could think of is Control Magic, but I love the card too much to get rid of it. Another option could be a Wasteland, but I don't think I'd feel comfortable going down to 2 Wastes.
2 Blood Moon is all you will ever need. When I ran this in Worcester I had that in play/in hand more than my win condition.
