Dialga ex Yanmega ex Deck Breakdown

Dialga is currently a very strong deck, largely due to its effective use of Mew. Dialga enables early energy ramp while also taking advantage of Mews Genome Hacking against decks like Palkia, without discarding any energy. Additionally, Cyrus is a powerful tool in both variants, as Dialga's Metallic Turbo attack applies early chip damage.

Yanmega is more of an anti-meta build, as it can one-shot Darkrai and Weavile, making it a strong counter in the current environment
