This is such a super strong open that almost all proxy multishpere meta files pack it for its 1sp up to lvl 4 merc death which basically wins games especially if lvl 4 targeted.
I am fine with this card in augmented files but I think it needs to be changed to stop ot limit it being using in other ones.
It is so good some files even proxy just to use this in files usually with no other lawtia cards in their file. And do not tell me it is hard to mulsphere. With cards like proxies,moxies,chaos strong hold it is so easy. Also all guys pretty much have it so abuse is rampant.
I suggest changing open to something like the following:
Conditional use atleast 10 augmented or abyssal forces cards in file/grave/removed.
(edit thanks muklas)
reduce lawtia lvl to 0 and reduce all other sphere levels to a max of 2
Or add start skill
Set one when random non lawtia friendly unit to hp=0
I am sure other people feel the same way.
That way it is more balanced when used outside augment
