Skhrimsch, the Bonesmith

When you cast Skhrimsch or another Skeleton
spell create a number of Bone Tokens equal to
the number of different colors of mana spent
to cast that spell.
Bone Tokens you control are equipment with
"Equip: {1}" and "Equipped creature gets +1/+1."
Equipped creatures you control have
"Ward Pay X life where X is the number of
equipment attached to this creature."
