is 9 atk for 9 quanta or 11 atk for 9 quanta really considered a rusher?
Not really, but it does kind of fall into a midhitter GoTP range, which a mono-light does lack unupped. (Guardian Angel only fills midhitter niche upgraded. Pegasus and Crusader require off-element quantum for full potential.)
While the card is nice either way, it might help 'complete'
more than it contribute to Fire given the appropriate tweaks. On the other hand, it adds some needed thematic variety and flavor to Fire but does risk crossing over with Phoenix and Dragon if it does so. I would personally prefer Fire if Elements gets more cards on a regular basis. As Atico stated, we don't get many cards in our updates - given the fact that certain Elements are not 'complete' structurally yet and that we still have a rather small card base, new cards should at least try to help out such Elements that lack completion rather than be there solely for flavor.
As for potentially changing the card to mono-
, I disagree with this idea. While Seraphs are angels, they share strong thematic ties to
and their name literally means "burning ones" as stated by Napalm. Attempting to tie the card to protective effects (such as the Anubis-like one suggested earlier) in the thread steers the card to a might more light-like theme and seems to completely clash with the
theme it coincides with.
Overall : I'd prefer this card became more GoTP-like in nature, except as
instead of
. This doesn't seem like the best card to help refresh Fire's variety and it's niche seems to be better off as fitting an open space in
rather than an already covered one in Fire.
