In the literal sense, Caetus is a clear winner)
Each starter deck includes: 1 Preconstructed deck of 60 cards, including 2 foil cards of the characters on the package front
Youre likely to get permanents much larger than just five mana for your five Treasures, and the ability to activate Magda at instant speed makes it difficult for your opponents to stop you
If you look at a (very fringe) Legacy deck nicknamed Zombardment, you'll see the deck is actually not that far from being portable into Modern
You get to put +1/+1 counters on it whenever you cast a creature, and since mutating counts as casting, you get to put a counter on your commander and grow it biggerto then cast more mutate spells
Youd think its activated ability would give it a home in decks that want to reuse landfall triggers and good enters abilities, like gain lands or surveil lands, or to reset a channel land that you had to use for mana during an early turn, but thats not how most people use it
