I really like the idea of this deck, even though it is easy to beat (did once, seen few more times) .. it could go with some changes, definitely.
As you play there Chambered Reef I miss there Flash Floods. Also once you play Ley Displacement it should be worthy to consider adding more Place Enchantments, I think. F.e. Claimed with Blood would go with this one very well.. I see the problem it needs 2 red domains, which would need other changes in this deck..
Something to get easily on 2nd flux would be handy as well (I cannot see the way now without putting in buildings site) - Thunderheard reach sounds good?
Just ideas which crossed my mind, I can't say if they are correct or not, need someone else to do so..
