You could do Longshot, Rebel Bowman with a bunch of damage and other non-creature spells (including job select artifact equipments, to put creatures on the board).

I have one, and I have Trusty Boomerang, so you can play it for free (and do 2 damage to everyone), attach for one, pay one to tap somebody's creature (and one of your own), and then do it all over again until you run out of creatures or mana. Toss Ravenous Robots in there, and each time you get another creature to tap on the next turn (and blockers). As a combo example. You get to do two damage to everyone, tap a creature an opponent controls, and generate a creature yourself for two mana, over and over.
