My advice is
3
Goblin Piledriver and
remove 2
Goblin War Strike4
Goblin Lackey and
remove 4
Warren Instigator - Basicly same card, but one turn soon
2
Goblin Bushwhacker and 2
Skirk Prospector, and
remove 4
Foundry Street Denizen - better ability for ALL your goblins if kicked and the other to acellerate the game
4
Lightning Bolt instead of 3
2
Sensation Gorger and
remove 2
Quest for the Goblin Lord - Your will be empty handed fast, this will allow you to draw cards and fuck your opponent hand
2
Ember Hauler and
remove 1
Raging Goblin and 1
Mogg War Marshalthis is my advice, but everyone has your own style of play and a budget to spend on magic haha
What did you think about my advice?
