So, does metal magic create metal, or shape metal? Sharing would be pretty useless in Combat and creation would be absolutely op for builders in the colony!
Moving on! There are a few new magical fields that I want to take a look at which might be good. Wood, Metal, Lightning and Force magic. I've heard mention of these as 'advanced' elemental magic which are a lot more common with higher levelled Delvers and Dungeon dwellers according to the golgari. Usually, one would skip over the basic stuff as fast as possible and then invest their time more effectively in these, more potent elements. At least, that's what I hear. Lightning is generally considered very powerful offensively, I only need to look to Tiny for that to be proven true. Wood and metal are common magics for builders and crafters, though also have their uses in combat. Throwing a spike of ice at someone is generally dangerous, sure, but throwing a spike of metal? More threatening to put it mildly. Then there's force magic. Good ol' kinetic energy. Wanna grab someone by the throat with magic in the most literal sense? This is the method! Care to throw out a claw and have a wall of invisible pressure extend outward, knocking down your well armoured but comically inept foes? Boom.
