What I really want is the new art for spellcasters and golems (well, I fell in love with the Luchuirp...). But the golems aren't that important, since you can distinguish them, except for the clockwork golem! I would be really interested in how it might look in the end...
yes, first would be clockwork and wood golem, then maybe mud golem. on the long term, the higher tier golems need a more unique look too.
