It's only the elemental hate that's wrong with this card. remove that, in one of the ways mentioned before, and then it should be fairly balanced.
The difference here is that in , it completely overshadows the existing cards presented. The cards you put here do not overshadow other cards in their own elements.
I think Aves has a point with respect to the creature set for the
element. This creature is clearly built to be high attack and low HP right now. This is quite out of tune with thematic balance of creature stats in
which are supposed to be relatively even or slightly biased toward HP.
Unupgraded Pegasus is one counter example, but this is partly due to its thematic tie in to the air element which favors higher attack creatures.
So while this creatures stats are balanced with respect to general cost to stat ratio in elements overall, it is out of place to put a creature in
that has a very high attack to hp ratio.
There is a balancing reason for this as well. It is because light as an element is based around healing, defense, and bolstering allied creatures through spells and skills. If you give it a high attack heavy hitter, it could very easily make
overpowered compared to the other elements.
In my opinion, the cards stats could use some tweaking before it is perfectly balanced.
So, between that and the elemental hate, I'm still not a big fan of this card at present.
I think it has some very interesting potential, but it still needs a bit of work.
