Each turn you have access to one of four powerful abilities
Gruul colors let you access most of the werewolves that have been printed, and Tovolar gives you extra ways to turn the day to night
Even without this combo line The Gitrog Monster can just be a value draw engine commander, making it a strong deck and worthy of a top 250 deck
Then you can lean into making Jolene a threat that can kill players with commander damage, or just play big, splashy finishers to bludgeon your opponents into submission
With two cheap commanders in the Command Zone, you get to use Fierce Guardianship and Deflecting Swat for free, likely much sooner than your opponents, and much like Rograkh, you can offer up Silas to any cards that require a sacrifice to reap those rewards
If one of the tokens somehow is under another player's control as the delayed triggered ability resolves, you can't sacrifice that token
