It looks like the same manabase to me plus 2 flagstones, I was already not playing the Eldrazi temples except in sideboard games for the mirror/against shops.
I mean to me it looks like it is a straight substitution of tool craft exemplar for tks, but you don't actually always have turn 1 white mana with this deck, compounded by the fact that you would have to name dwarf or artificer with your cavern which makes subsequent plays more awkward, I just don't see it.
Yes you are probably more likely to cast a turn 1 toolcraft rather than a turn 1 tks, but it doesn't disrupt the opponent at all. If you want that why not just play porcelain legionairre at least then it always has first strike.
Smuggler's copter also doesn't disrupt your opponent at all, and you seem like you are behind in the mirror because your creatures are smaller on average, and your opponent has access to displacer. I get that having more options with copter is good, but you are still playing a card that gets hit by your thorn effects and isn't necessarily hitting harder than your creatures, if you are going to do that why not play equipment (I see that you are playing stony silence) but stoneforge + equipment does a similar thing to copter, and let's you cheat the mana costs along the way.
Edit: That all aside I will attempt to put together your list, maybe there is something to copter that I am not seeing.
