One of the joys of Commander is getting to play with so many groups of people, and one of the best ways you can prepare for that and make it a fun and inclusive experience is to ensure you have a breadth of decks that can be pulled out at different tables
And opponents are going to be wary about killing your commander due to the threat of you replaying it, transforming it, and getting even more emblems
If your deck is focused on this, some amount of milling to power them up can also be reasonable
But no mana washing, so if you run him don't run Arcane Signet or Rakdos Signet, but Fellwar Stone and Manaliths that tap for all colors
Sort in between other activities if you have limited time I regularly watch what they call second monitor content, where a video can be playing on your screen and you dont have to actively watch it
