Wizards releases new pre-cons on a regular basis, so simply find a theme or color combination that piques your interest, and get playing
Against fully tuned Commander decks, precons can feel underpowered until you start upgrading them with stronger staples or additional synergy pieces.
After all, they are mostly (slightly) overcosted spells on one side along with a land (which often comes into play tapped and always only taps for a single color of mana) on the other
While not a starter or a legendary, its gimmick allows it to stand out across multiple generations
While not as expensive (mana-wise) as Emrakul, Ulamog, the Defiler still comes in at an impressive ten mana to cast
My only gripe with the deck was that it found an optimal build of small creatures whose abilities scale with their bodies and it hasnt really needed to innovate beyond that, besides the addition of The Ozolith and The Great Henge
