Da Vinci Artifact shenanigans EDH Deck Tech 

very cool commander and deck. What is the Clock of Omens combo you mention a few times? Training Grounds can make infinite colourless mana with an animated Basalt Monolith (it will only cost one mana to untap). The backside of Enigma Jewel can make infinite mana with BM too. Intruder Alarm and an animated mana rock that can cover LDV’s ability would let you draw through as much of your deck as you like too
