Sundering Growth and Frenzied Goblin are in my cube. They're not flashy, but a flexible Disenchant with upside and a 1-drop that can push through damage are both valuable.
I should probably play Genju of the Cedars, since I run an enchantment theme in BGW.
Foundry Street Denizen isn't nearly as good in limited as it is in constructed. Red has a lot of superior 1-drops.
Genju of the Spires is awesome but fragile.
Hell's Thunder is playable, think of it as a Lava Axe though and decide if you want to run that.
I wouldn't include Gerrard's Verdict over other
options, and as a gold card that means it will (probably) never see play in my cube.
I cut Staff of Nin, but could easily see myself adding it a again. It's an innocuous looking card that can really turn games around.
