I would add monastery swiftspear if I was making an update burn deck also change flames of the blood with skullcrack I would add eidolon of the great revel street wraith and finally I would add magma jet for a couple of browbeats.
Why goblin rabblemaster insted goblin chieftain
I would take goblin geanade out and replace with massive raid
It's a great casual deck but to make it modern take out goblin war strike and replace it with massive raid
