Halp? 3: Halp Harder

[CbStrad]

So I'm wanting to help my girlfriend build a modern Grixis Goblins deck. Any suggestions/staples? I know {Goblin Guide} and {Warren Instigator} are staples, but what else should I look for?

 {Goblin King}
{Goblin Bomb}
{Goblin Bombardment}
And all the Tuk Tuks have always been Goblin staples for me.

I wouldn't go grixis on it. Goblins are either mono red or rakdos colored. I don't know much good goblins but goblin shortcutter makes it a little more aggressive
