Banding is a similar concept: when your creatures form a band, they can all attack or block together
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
This doesn't target any permanent or player, but it must be able to enchant that permanent or player
Sword of Hearth and Home and a way to either attack with another unblocked creature that can flicker Aurelia or a way to auto-equip, such as Ardenn, Intrepid Archaeologist, can help combo in this way
Later in the game when everyone has some artifacts and enchantments it can provide you with a huge infusion of mana you can use or save as needed, and lets not forget that sometimes what youre looking for are a bunch of tokens themselves
