somberwald only helps for creatures, not useful with door :/
More Gilded Lotus es and add some sweepers instead of the Fog effects! A sweeper like Day of Judgment forces them to rebuild their board whereas Fog only delays them a turn. Gilded Lotus is absolutely perfect for activating the door, especially since you can cast Phyrexian Metamorph copying it the turn you play it, setting up for a win on the very next turn! +1 from me.
Thanks for the +1, What do you think of the land base as it stands?
