RATE MY MACHINA DECK?!?

i don't know machina's... but can't you only special summon machina force with commander covington? or is there another use that i just don't know aobut because i never really go into them. that's the only question i have... everything else looks good. i think maybe drop a smashing ground for a swords of revealing light, and drop a solidarity for soemthing else (because running 3 cards frequently makes dead draw them, so i noyl run 3 of something i can use NO MATTER the situation)
