Its far and away the most powerful preconstructed Dragon deck, but if youre looking for cheaper alternatives, my first deck was Draconic Destruction from the Commander starter decks, and Temur Roar is a great three-color dragon deck with upgrade potential, too
In that case, this card allows you to draw extra cards and keep some card advantage
I think Animar's reputation as being "unanswerable" is a little too much
You could even go for a Cat Tribal subtheme with Marisi, since Arahbo, Roar of the World doesnt just work from the command zone
If youre looking to bring a unique group hug deck to your next game or perhaps some immensely powerful land-based strategies, these non-black commanders are the way to go
Some commanders have certain interactions which dont actually impact the game state but CAN be looped to generate an arbitrarily high storm count
