Okay, since no one else has bit yet, I will. There are a few cards that you are playing that I think could be, shall I say, better.
on the removal front:
1.
Krosan Grip is a very good spell. It has been my experience, however, that
Return to Dust is usually much better in 5 color edh for 2 big reasons. 1. It Exiles the artifact (to bad, so sad
Darksteel forge), which is very important against
Sharuum,
Arcum Dagsson, and
Karn, Silver Golem builds. 2. If you cast it on your own turn its a 2 for 1, much like
hull breach (which I do like), only they are gone forever.
2.
Condemn. I don't really like it. I know someone is going to show up and tell me how wrong I am, and that I am a total idiot for not recognizing its absolute greatness, but I really don't like it that much. In the same color I think
Oblation is generally much better since you can hit any permanent and there is no "attacking" clause.
3.
Comet storm. I don't really like it. I think that
StarStorm is generally going to be much less mana for the same effect. That is unless you are just using it to burn out the table with infinite mana.
I also have questions about a couple of cards.
What are you generally fetching with
Crop rotation? do you have a normal target, or is it usually used for color fixing?
I am assuming that
power artifact is there to make infinite colorless mana with
Grim Monolith? How has that worked out for you? I am guessing this combos with
Comet storm to just burn out the whole table in one go? how has that worked for you.
Your not running as much artifact acceleration as I would have thought or expected.
DO you find that you reliably have enough Tutors, Sweepers, or draw spells?
Lim-Dul's Vault,
Beseech the queen,
Idyllic tutor, and
Wheel of fortune all seem like obvious choices for this deck, but maybee thats just me.
No
Iona, Shield of Emeria?
I actually really like the idea of your deck. I am guessing that it plays much more like a Type 1 deck than most EDH decks. I don't think its particularly douchie at all.
Linvala STAX is Douchie. Prison decks, generally (I am looking at you MBC) are douchie.
Dralnu Pitch-long is Douchie. Oath wins with creatures however and is, in theory activateable by any player. Seems prety board interactive to me.
have you considered playing
Reverse the Sands? I know it seems like a casual card ,but it does make the rest of the table fear "kicking the fat kid", since no one loves a table-wide mirror universe (except you of course.)
