Thats a lot of value packed into a $20 price tag
While it has a lot of low-cost cards, this isn't a hyper-aggro, go-all-in kind of deck
The fact that it then has the ability to trigger up to once every single turn its out simply makes it the best mana ramp white has gotten in a long time, and a contender for some of the best value too
You also have characters like Mim and Maleficent who might just be stronger dragons all on their own
It does a little bit of everything, gaining life so you can stabilize, producing mana, and even putting a clock on your opponents
As a deck can only contain cards within the chosen commander's color identity, the more colors within a commander, the more options you have when selecting cards for your deck
