How to optimized the mana curve for your commander?

I’ve been in the process of trying to be more purposeful in setting up my decks’ curves (all 1 and 3 mana ramp in Pantlaza, a bunch of 1 drop fliers for Breena, etc.) and I’m curious how that looks for other commanders? What commanders want to be ramped out vs played on curve? What do you occupy those non-ramping non-commander play turns with?

My next curve overhauls I want to work on are Captain Howler, Skullbriar, and Ghave, if anybody has any specific support/experience with them
