So my latest search through Gatherer has proven itself fruitfull. I found four cards that looked nice.
Lodestone Golem - might be sideboard material.
Servo Schematic- It works fine with Grinding Station and Greater Gargadon, allowing for three artifacts to be sacrificed with one card. No cantrip though.
Treasure Map
Flip - Scry for 1 might be nice. And card draw later on. Might be too slow though.
Riddlesmith - Saved the best for last! A definite 4 of! Looting effect on cast, allowing my "eggs" to both loot and cantrip. Great when I try to go off, discard unwanted lands and get more gas instead.
