If you just do a bunch of nothing on your first three turns and hope to cast some exotic six drop off the back of this on turn four and not just be totally and completely already dead then you are perhaps too full of optimism
The amount that works for you heavily depends on the size of your collection, your preferences for power-levels, your common playgroups, and mostly how often you get to play Commander
For example, if the target historic permanent card is an artifact card (but not a creature card) and you control March of the Machines ("Each noncreature artifact is an artifact creature with power and toughness each equal to its mana value."), it will enter with two additional +1/+1 counters on it because it will be a creature on the battlefield
SHINY RAINBOW CHARIZARD VMAX Simply stunning
However, despite a relatively tame collection of cards that don't feature any chase cards that will soar into triple-digit values, there are still some solid cards in the Sword & Shield base set
The issue is even mono-black likely wants to run some colorless lands and Archenemys it is not so good that it is on its own worth building around
