The one downside, I guess is that the loot isnt optional, so you might have to be a little careful sometimes, but thats really splitting hairs
While this build focuses on controlling the game before it busts out big enchantments to overwhelm the opponents with card advantage, you could take it down a couple of different paths
There you can copy your Commander and then both it and your copy are drawing the cards, as well as other copies of Commander that you made with things like Clone
Suffice to say, there are plenty of foil uncommons that have gained value over the years
The deck starts by casting a number of efficiently costed creatures with strong secondary abilities including Malcolm (loot/draw effects), Breeches (create treasure/unblockable/draw effect), Staunch Crewmate (draw effects), Captain Storm (+1/+1 counters), and many more
As of this year, altering cards is my full time job and I generally have a month-long backlog of work at any given time
