Its a common thing to hear that every mechanic in MTG is a variation on kicker and split cards
At time of writing there are 291 different cards with serialized versions, although there are one or two duplicates in that list, like Chromatic Lantern getting serialized versions in both Ravnica Remastered and The Brothers War
The beauty is it isnt an end-of-turn effect, so the copied artifact can be used for multiple turns
Each effect exists on other cards in various forms, but having them together in a nice, neat, two-mana package is excellent
If you must play with outside cards, discuss it with your group
So, here's the plan: we get a Cryptolith Rite on the battlefield along with a Paradox Engine (with the help of Whir of Invention, if need be), which means we can tap all of our creatures for mana of any color, and then whenever we cast a spell, we get to untap all of our creatures, which allows us to tap them again for even more mana
