i was saying for the version where common ancestor is more powerful based on how many creatures of that element. to clarify agian:
for the current version where ancestor is a 2/2, coalescense should cost more or equal.
for the discused version where ancestor is an x/x where x is equal to the number of creatures of its element in play when it is played, it should cos more because ones played with fractal or mitosis will be stronger than the first, and quickly generate huge ammounts of attack for cheap. the fact that coalescense generates multiple has nothing to do with it. in the proposed version, coalescense will always generate exactly as much attack power as the number of creatures in play. an ancestor will generate the number of attack power of the creatures of its element. this is technically not as much, but the fractal abuse is evident, as each ancestor will be stronger than the last.
