I’m trying to brew up some new decks and a commander style/type that I keep returning too are commanders that give an ability to all cards or cards of certain type in your deck.

Some examples:
[[cayth famed mechanist]]
[[sami wildcat captain]]
[[tannuk steadfast second]]

Is there a term for this so I can look for all of them on scryfall?

Do you play any commanders that grant an ability to other spells? Are they fun? Get stale fast? Looking for any recommendations!
