It seems like just running a pinger would be better than waiting for FF.
Razorfin Hunter is fairly solid for 2cc Also running Merfolk looter + Anger is solid...
If you go with the

artifact creatures you can go infinite with Welder rather than curio. Mana Myrs can be nice in that spot as well... seeing as how they untap when you play a creature for infinte mana. I had a deck like this called 21 Gun Solute. No need for Curio/Future sight when you have welders, mana myrs / helm, pingers, curiosity, merfolk looter/anger, and archivists.
Kiki-jiki + Pinger + Alarm = GG
