Fortunately, there are ways to cheat, like playing many changelings or cards like Arcane Adaptation to make everybody in your deck a doctor
Jeskai Flashback: If you're playing the Commander 2019 decks straight out of the box, it means that Sevinne, the Chronoclasm is your commander, and I (as well as the community at large, based on our preview rankings) think it's the worst of the face commanders in Commander 2019 by a pretty significant margin
Commander is one of MTGs most popular formats, allowing groups of four players to face each other with 100-card decks and their life points increased to 40
Luckily, you'll only want to add one or two to the deck anyway, so you can buy a couple of the cheapest to replace inefficient lands like Bad River and Krosan Verge
In Commander, because of how many good cards have low mana values and your life total of 40, its much easier to make Ad Nauseam work
Theres savagery to be had here and Im all for it
