it makes no sense if every element has the same opportunities
Light will still have Blelbinems and Darkness will have its Devourers and Vampires. One similar card doesn't make "same". Like, Wyrms and Pegasii both Dive and yet you aren't complaining.
Also, keep it Light only - this on Life could be too strong with all the Frogs and Cocks you can get out real fast... on the other side, Skeleton spam exists, but Frogs/Cocks have enough HP to survive a RoF, and Skeletons don't. So.
