If you want to capitalize on MI, you could also try the old dredge route and give Dakmor Salvage a go to help get that Hulk in the grave. A bit risky but something else to add to the pot.
I can't find the link, but I seem to recall TWoo posting up a deck tech using Hornet Nest + Blasphemous Act which looked like a LOT of fun. Maybe not what you're looking for but perhaps can provide some inspiration?
I run a RG version of Infect that eschews all Exalted effects and goes for doublestrike via Assault Strobe, Ghor-Clan Rampager as it can't be redirected by Spellskite, and runs Simian Spirit Guide for the surprise factor. It's a bit of a glass cannon and often mulligans but is still super fun. If you are against the prices of the normal infect pieces like the Noble, this might be a direction to look.
I loved building and playing it with my friends. It's a feel good deck for me even when I don't win. It's got a lot of 'old school' Magic flavor so having it in your arsenal is great. Points if you rock the old Antiquities versions of the Tron lands.
There is a fun build out there that utilizes creatures that tap to drop lands (Skyshroud Ranger, Sakura-Tribe Scout, etc.), Intruder Alarm, and Meloku. Essentially it becomes:
-Have Meloku out with one untapped land
-Tap the land for mana and use Meloku to return it for a 1/1 flyer
-Intruder Alarm untaps all your creatures so you can tap a creature to put the land back into play
-Rinse and repeat until you have a million 1/1 flyers
Super janky but almost guarantees a hearty chuckle if you can pull it off at your local FNM
Can you spend the 2 mana from Eldrazi Temple to turn over a manifested Eldrazi creature?
Thanks!

Check out Kiln Fiend as well. There is a deck out there using him, but the name escapes me; it's very similar to what you are going for here.
