would switch out Embermage Goblin for Goblin Welder partly due to the embermage's full effects won't go off, lowers the total CMC, and say one of your artifacts used to go infinite is destroyed, you can easily just pop an artifact that isn't doing much at the moment to get is back since your running no artifact recovery that I can see and 29 artifacts. +1 though for a fun looking cheap build :)

TheHamster, I had looked at Goblin Welder as a useful addition.

I wanted to include Embermage Goblin as another tap for damage creature to pair with any of the deathtouch artifacts.

Currently I have 2 artifact recoveries (however, I may need more); Buried Ruin and Trading Post.

Since you pointed it out I very well might switch the 2 as there are 4 other creatures that tap for damage and an artifact that allows creature to tap for damage.

Goblin Welder will give me another artifact retrieval which will be very handy.

Thank you for the suggestion and upvote

another thing I would consider running (it's worked wonders for me) is Goblin Charbelcher it fit's your tribal theme and the amazing part about it is that the cards are revealed BEFORE you choose who (or what) you target. Since your running a lower than normal landcount it's even better
