I think the likely path well want to take is looking at what sweet gold cards are printed (as well as any possible busted mythics), look to see if those fit, and then build around them
But dont let anyone trick you, so put a fair price for your collectibles
The deck also has too many 5-mana cards, so Im not eager to slap one into the command zone
Whether you like it or not, Commander's politics affect everyone and each player can form secret alliances as an accepted method of play
Breeches lets you steal the top card of your opponents libraries so long as a Pirate dealt damage to them, and Malcolm gives you Treasure tokens to cast them with
Also note that this is part of the Commander deck led by Y'shtola, Night's Blessed, which specifically cares about casting noncreature spells with mana value 3 or greater
