When you can't maindecking your own pet cards... a flying Hill Giant just isn't what it used to be, and UG is doing more powerful things.
Tower Gargoyle and Fleetfoot Dancer are on watch, though with the right mana, at least they have square PT.
Trinket Mage in so that whoever goes for Longbow/Crab can reliably find it.
Undying Rage might be good? But it never feels like what red wants to do. It's just Goodstuff, a fair Rancor.
Spikeshot is a weird 'in' when that comes out, but plenty of things to boost its power.
