2. I want to ask a question too: Do you really play with Chaos Orb?
-Sure. I have a Collector's Edition orb. If i think my opponent is going to have a problem with it, I wont use it. Simple enough...
3. What about Acquire from 5th Dawn? You can search your opponent's deck for artifacts and bring them into play.
-That seems like it would be really decent in casual circles right now since so many people are trying out all the fun mirrodin block artifacts. I like this suggestion.
4. I think you could need more draw power (perhaps thirst for knowledge, rush of knowledge or even treasure trove)
-I used to play rush of knowledge a few months ago, and it got the axe. More card drawing could help against counterspell-oriented decks, since more threats are obv. necessary.
5. A little more graveyard recursion would be great (why not try to splash red or white for goblin welder or argivian archeologist? A friend of mine works with pemmin's aura on goblin welder

)
-I purposely stayed away from other colors. Yeah, welder is pretty sick, and I could have gone to black's tutors for more consistency, but I decided to limit myself to one color for "creativity"?
6. When looking at your list I guess your group doesn't play counters but nonetheless you need to protect yourself and your combos so another suggestion would be to play something like leonin abunas or fountain watch (at least they can come into play faster than darksteel forge)
-Well, against countermagic, you have to play careful. There are quite a few spells that if they resolve, they are a headache for whoever is across the table from you. Without some kind of continuous card-advantage engine, you can find yourself out of steam. They can't counter everything, right?
I hope that this will help you a bit.
-Absolutely. Thanks for taking the time to post.
