The free deck analyzer will tell you how many your list currently has
I used the shell of a mono green ramp deck and inserted my Eldrazi package into it and the results were good
Culling the Weak, Ad Nauseam, Rhystic Study, Demonic Tutor, and Thassa's Oracle, for example, are among the strongest cards in Commander, and Dimir decks have access to all of them
I wont be adding lands to this list unless they have added utility beyond tapping for mana, since we also have a comprehensive breakdown of all Abzan lands in Magic
The Cards Credit: Wizards of the Coast Space Beleren FromTheShire: This creates a fun sub-game which I'm always a fan of, and cards that further mess with combat like Pramikon, Sky Rampart seem like a good place to be here
for example, your cool counterspell should be blue, your hasty creature is likely red, a card that cares about power is green, and so on
