Yesterday I tested the UGR ***** match-up and the Life from the loam match-up with the following list.

2 taiga
2 badlands
4 mountains
3 bloodstained mire
3 wooded foothills
4 wasteland
4 rishadan port

4 goblin lackey
3 mogg fanatic
4 goblin piledriver
4 tarmogoyf
4 goblin warchief
4 goblin matron
4 goblin incinerator
4 goblin ringleader
1 goblin king
2 siege-gang commander


4 aether vial

I must say it dramatically increases your match-up.
What I found out was that mid-game my goblins were either burned to a crisp or that I had to throw away gobs to protect me from opposing goyfs before I played the goyf myself. Now I can make midgame a stalemate and get to end-game where my card-advantage gobs do the work.
Altough I don't have to many illusions about the post board match-up (pyroclasm is massive card advantage for the ***** player) I do think it's a step in the right direction.
Post board I am thinking about several options.
Smother -> handels everything but mongoose
Dralnu's crusade -> effectively limits the power of burn. fire/ice wouldn't be card advantage any more and pyroclasm would only kill the little guys.
Advantage of the crusade is that there is fairly little enchantment hatred in our meta game and that most ***** player side out some counters post-board. The fact that it is rather slow does not really matter because you are aiming on the late game instead of just racing.

general note: I think it just shows how insanely powerful the goyf is.
