mtg shiny cards Magic The Gathering Dominaria United Single Card Rare King Darien XLVIII 344 Textured Foil With 2 mm soft cushioning Spellseeker (foil-etched)

Unfortunately the ability can only be activated on your turn, but with the aggressive leanings of this commander I think you want to be going for the acorns anyway

An Anthem effect

Perfect for quick starts and two-player games, making it ideal for beginners and seasoned players alike

This card mills its controller three cards and then allows them to return a Creature or Planeswalker from their graveyard to their hand

An added bonus: if your parents ever walk by when you cast this card, you might get a free chuckle when they say, "You mean the Rat Pack, right?" Sorry, mom and dad

It also, perhaps unsurprisingly given the title, promises a ton of new Dragon support
