Well spell damage, yes I believe that's what the Evoker abilities do have a look at them.
Mana cost for tactical spells.. yes... look at Ironeer blood and the Path of the Mage for examples. Not sure about Strategic spells, probably no.
Mana per turn, not easily as far as I know.
Per Shard effects, you'd have to elaborate on what you mean.. or what you'd like to do.
