an upgraded creature should be upgraded, not downgraded.
Obviously, the Elements Community definition of "upgraded" differs from your definition.
fabian771: An upgraded card is always bigger and/or stronger than its unupgraded version.
Elements Community: An upgraded card is always
better than its unupgraded version.
In the particular case you mentioned, Phoenix is an expensive card that can take a few turns to play and can be difficult to Fractal. Minor Phoenix is better precisely because it is so inexpensive. At only 2
, Minor Phoenix often can be played on the first turn, immediately after playing the upgraded quanta sources. At a maximum costs of 16
, Fractaling Minor Phoenix is a piece of cake. (Compare to a maximum cost of 56
to Fractal Phoenix.)
TL;DR The lower cost of Minor Phoenix makes it easier and faster to play. The large increase in speed more than compensates for the loss in attack power.
