Didn't want to read through 50 pages to see if this has been done before but I think something like this would be cool:
A
![Darkness :darkness](https://elementscommunity.org/forum/Smileys/solosmileys/../../../images/Misc/darkness18x18.png)
scorpion with one or zero attack and can additionally to the normal poison, poison a target (player & creatures) if cloak is active on your side of the field.
A life creature that starts with 10 cost and 8 atk. it can then split for the cost of 4 quanta in two creatures with all stats and (skill)costs halfed. thus 2 creatures which cost 5 and 4 atk and can each split for two quanta. they can split again. so the third split gives two creatures with 2 atk, costs 2 and can split for the cost of 1 quanta. splitting it again gives a 1 cost 1 atk creature which can't split anymore.
I think over all stages the hp is equal to the atk. the splits help to evade creature control and to synergies with feral bond. it also works nice with mitosis, fractal or twin universe.
in case this is too strong you can also say that if you don't split it the next turn it loses its ability to split.
in water i always wanted a weather based card, like rain or hurricane. not sure though what their effect should be
![Tongue :P](https://elementscommunity.org/forum/Smileys/solosmileys/tongue.gif)
hurricane could be a spell that you have to sacrifice a creature for. you can then destroy as many permanents as half of its atk. odd atk would be rounded up. so by sacrificing a crawler you could e.g. destroy the enemies weapon and a pillar.
guess that's it for now. hope someone like the ideas and that they haven't been done already
