Run a lot of artifact ramp- 15-20 pieces. You want to get Oona out early and keep up protection
Play a lot of two-card infinite mana combos. Probably all of them.
Aggressively tutor for Urborg to make big black mana better.
Ideally, you want to include Palinchron since it can go infinite with a lot of lands that tap for multiple mana.
This is not a 75% deck. This is going to be cEDH or 90%. There is nothing about this deck that is fair, the only thing that differentiates the power level will be the number of tutors and the number of free counterspells you run.
