Quote from the announcement explaining the new mechanic:
Cards in this release will incorporate a new mechanic that's fitting for the set: incorporate! A card that incorporates adds an additional mandatory mana cost to another card, and that second card gains additional attributes/text. Incorporate perpetually adds an additional casting cost to that card, adding any new colors from that cost, and adds abilities/text to that card for the rest of the game.
Or TLDR: Makes your creatures cost more but come in beefier.
Hey! Wanted to toss a quick note that we did update the language here for clarity and accuracy to the following:
Incorporate perpetually adds an additional casting cost to that card, adding any new colors from that cost, and adds abilities/text to that card for the rest of the game.
