Making Skeletons (for fun)

Lord of Bones
Pretty powerful card, but lacks coherence to be honest. 
Paying to create a skeleton token for each creature that dies seems pretty reasonnable, but I don't see how dealing 1 damage to target creature, player or planeswalker makes sense flavor-wise.
In MTG, a "lord" is also a slang term for creatures that give +1/+1 to every creatures of the same type you control. A good example of this would be Valiant Veteran. It's just a suggestion but I would go for this if I were to call my card "Lord of Bones"... 

Lady of Bones
First ability is okay, second ability is pretty good, but I still don't see how these would go together in the same card. 

Wall of Bones
At first, deathtouch for a 0/4 didn't make much sense to me, but the +1/+1 counter for each skeletons that died makes sense. This might be your best card flavor-wise. But I think this ability is a bit too OP for a creature that costs only . Plus, the fact that it gets a +1/+1 counter each time a skeleton dies seems too strong. If I were you, I would do something along the lines of :

Because having a lot of skeletons-making creatures in your deck, this card would be very strong very quickly. Definitely needs balancing



Overall, good set of abilities (a bit too strong imo) but not that good flavor-wise, except for the Wall of Bones.
