I am not sure I want to run 4 Daretti..

Maybe 3/4 Dack and 2 Daretti and still go with the Dack combos with Notion Thief, Treasure Cruise, Jam Mox Diamond, Liquimetal, Welder.

I am not sure I can justify 4 Daretti's when I could play Jace in any deck. I also prefer to run more of the cheaper cards (Dack, Welder) than 4 of the expensive guy.
