I played a quite similar deck in Duelmen and was quite successful. I did not include the black-splash, which I personally think is not needed.
Here is what I played:
Mana:
1 Black Lotus
1 Mox Emerald
1 Mox Ruby
1 Strip Mine
4 Wasteland
4 Taiga
4 Wooded Foothills
3 Forest
3 Mountain
Critters:
4 Blurred Mongoose
3 River Boa
4 Gorilla Shaman
3 Grim Lavamancer
4 Kird Ape
4 Mogg Fanatic
Burn:
4 Cursed Scroll
4 Incinerate
4 Lightning Bolt
Utility:
4 Naturalize
Sideboard:
2 Artifact Mutation
3 Pyrokinesis
4 Pyrostatic Pillar
4 Red Elemental Blast
2 Tormod’s Crypt
I did not use Troll Ascetic, because of the 2 green mana. But they are very nice, and can be included if the manabase is adjusted slightly. Treetop Villages help, too. I did not play them by that time (today I do).
Against Goblins (which I feared too

) I had the Mogg Fanatics, which proved to be very valuable. Scroll and Lavamancer came close on MVP against Gobos.
Blurred Mongoose is a tough challenge for a Keeper-deck, which is heavily played by very skillful players in Germany. They helped a lot to win 4 matches against Keeper in Duelmen.
