mega booster box Evolution - with Topper (EN) Cards vary by pack. Pokemon Mega Evolution (ME01) ENHANCED

I think I'll need to build a Standard deck that runs this and Underfoot Underdogs to see if I can pull off the combo just once

P/T Number 317 Language English Legal Formats Alchemy, Brawl, Commander, Competitive Brawl, Historic, Legacy, Modern, Pioneer, Standard, Timeless, Vintage Rulings (6/6/2025) Each face of a nonmodal double-faced card has its own set of characteristics: name, types, subtypes, abilities, and so on

Any suggestions are welcome

Unfortunately, this deck might not have the speed or power required to be a top contender in the current standard format, given that it requires multiple turns to fully set up a Phanpy or Spiritomb but Donphan still has potential, nonetheless
