My final piece of advice is to also consider tutors that arent on this list if they make sense in your deck
For example, Nicol Bolas the Ravager will exile himself and return to the battlefield transformed into Nicol Bolas, the Arisen by paying four generic, one blue, one black, and one red mana
Cards like Etali, Primal Conqueror have an even bigger impact on the game for only one more mana
Angels really need a viable multi-colored Commander, at the very least one that has an Orzhov identity, and the more colors the better
Proxies may not be of the same quality as actual cards and may not shuffle or handle them as well
Now you can sacrifice tokens, so thats good, but this is at sorcery speed, which means you cant sacrifice something when its targeted by removal or something
