Ditto on Skullclamp, great include.
Tiny robot variants could be interesting...
I scheme it would be cool if you could give Hope of Ghirpur haste with Lightning Greaves or Hall of the Banditlord. (Maybe its a bit cheeky)
Hangerback Walker is worth remembering , and Empty the Warrens. This is because, as Saffron Olive pointed out, this plays to Cheerios strength as storm deck. Unlike other storm decks, your blue opponents can't sit on counter spells and stop your storm chain at the last possible moment. VS cheerios one has to stop the first and next glimpse, immediately. If you get stick more than 1 glimpse active for a turn you are almost unstoppable. There is a lot to be said for posing a threat on the board, that is if one plays things like Bushwhackers or Haze of Rage
On the odd occasion riding a few empty the warrens Goblins to victory is most fun.
Hangerback for 0 sometimes keeps the chain going
If your' willing to dabble in black, Yawgmoth's Will gives one great ability to fight back after an initial salvo of control.
