It's a good idea, but it kinda steps on the toes of destiny and chaos lord. We have other FGs that have some overlap with one another, but they rarely have a complete overlap in core strategy - the only difference between the core strategy here and destiny's core strategy is SoR.
If you want to differentiate it more, maybe try making it a time/life (plus QTs and maybe even splash cards still) and going for mitosis/egg (and SoR). You could also go for eggs and phoenixes or eggs and air or some other bird-y themed thing that would give it a far different feel from the existing FGs.
