A less obnoxious move is to use a card like Nissa, Who Shakes the World to animate a bunch of lands to mount a go-wide attack or using the Liquimetal to make a creature into an artifact at instant speed to take advantage of Tempered Steel
Bronze Guardian also comes with the upside of being a brutal attacker since its power matches the total number of artifacts you have out, and if that wasnt enough, it has double strike too
Astrologian's Planisphere This two-cost Blue artifact Equipment with job select Equip for 2 will make it a Wizard and then as you cast non-dorks, toss a +1/+1 counter here and then on your third card drawn each turn, not just yours - brilliant win con there for Spellslinger brews and Commanders for Commander Damage in Cantrips
Whether you care about the number of artifacts you control or you have a way to double tokens, you should think about the Battleball
They use an "open air" card frame and special rainbow foil treatment, with a holofoil treatment on the icons and a gloss treatment on the artwork
