Let me get to a deck list and we can talk after.

3 Ornithopter
4 Puresteel Paladin
4 Vault Skirge
4 Dark Confidant
4 Memnite
3 Stoneforge Mystic

Spells
4 Thoughtcast
4 Cranial Plating
4 Paradise Mantle
4 Bonesplitter
4 Dispatch
2 Mox Opal

Lands
4 Ancient Den
4 Glimmervoid
4 Seat of the Synod
4 Vault of Whispers

So basically the deck relies around having an extreme amount of free card draw + typical explosive starts of affinity. The entire deck is full of combos and synergy and is just a ton of fun to play. With all the 0 CC cards + easy first turn play Dark Confidant is gold. Puresteel allows you to draw cards + equip for free when playing springleaf drum 2.0 and Cranial Plating. Stoneforge finds Cranial Plating which is the card that wins games in Affinity. Ornithopter and Skirge are good evasive creatures which add to the artifact count and carry equipment well.

Any comments or ideas on tweaking?
