There are plenty of ways to turn those creatures into more value, and some can even synergize with the decks core theme
Red + White Burn tends to alter combat and/or provide life (Boros Charm, Lightning Helix, Intimidation Bolt, Aurelia's Fury, etc.)
Thanks, (but) I hate it
The first is that whenever a Creature you control becomes blocked, you can choose to return it to its owners hand
Using this deck puts you right at the forefront of whats happening in standard, and nabs you a few rares that should keep their value for the foreseeable
Take a look: Weirdly, this particular rambling McNally has never seen a reprint, so any copy out there that you might see is forever just Creature Construct. As per official rulings, it is indeed an artifact, if you couldnt tell by the frame, the colorless casting cost or the general animated map-ness of it all
