I rocked goblins in my Boros deck alongside my soldiers before moving them to a Rakdos deck. focus your mana source on red/white if you can (
boros guildgate,
temple of triumph,
stone quarry,
wind-scarred crag, basic mountains, and basic
plains. this will focus your mana). I would use Bolt of Kerenos (cc3, cheap damage to opponent)
Elspeth, Sun's Champion (cc6 +1 loyalty=+3 1/1 white soldier tokens.. and an emblem thatgives all your creatures +2/+2 and flying),
Massive raid (cc3, does damage equal to number of creatures you control... deadly in a token swarm),
Assemble the Legion (cc5, amasses an army of tokens in no time as you add more and more each turn),
Impact Tremors (if tokens count as creatures, this cc2 will hammer your opponent without you even having to attack), Conquerer's Pledge (cc5 add up to 12 1/1 white kor soldier tokens),
Gather the Townsfolk (cc2, +2 1/1 humans; +5 if you are real low on health),
Raise the alarm (cc2, +2 white soldier tokens),
Impact Tremors (each time you add a creature to the battlefield, even tokens, the opponent takes 1 damage.. and its cheap),
Hordeling Outburst (cc3 +3 goblin tokens),
Dragon Fodder (cc2 +2 goblin tokens),
Goblin Rally (cc5 +4 goblin tokens),
Krenko's Command (cc2 +2 Goblin tokens). hope this helps make your token swarm even deadlier
this will show you are VERY spell heavy... but those spells are worth many tokens and tokens can over run your opponent before they have the mana to cast a significant defense. I defeated a cheap
drain life deck by using the cheap tokens to over run my opponent quickly (I only had 2 mana the whole time, but hammered them by attacking with tons of tokens) hope this helps your goblin deck get stronger and feared.
