Dialga ex Melmetal 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.

Melmetal is surprisingly viable due to Giant Cape, which significantly increases its effective HP. It can survive even 150-damage attacks, especially since Giovanni is currently not being played.
