dragon shield sleeve card Standard Dual Matte Justice Deck Protector Sleeves sized sleeves for trading cards measuring up to 63 x 88 mm (2 ½ x 3½ inches) Dragon Shield Matte Sleeves (Turquoise)

It's flexible, political, and lets you laugh off removal-heavy pods

Five-colour decks are often difficult for newcomers to play with, and the last time we saw one was in 2017s Draconic Domination deck led by a creature that has become a big name in Commander in the years since: The Ur-Dragon

You also have Ashcoat of the Shadow Swarm and Karumonix, the Rat King (the only legendary rat who isnt from Kamigawa)

Since they will each have a large individual impact, you don't need to necessarily cast a lot of thembut the second one tends to seal the deal

Effect wise, I think you could add an effect that strenghtens the summoned monster or protects it from leaving the field for the rest of this turn
