In my opinion, Vetruvian golem is just better than Lyonar golem can be. Maybe not in every way or by every metric, but still, better. You have sirocco and cataclysmic fault for wincons, blood of air, sandswirl reader and maybe falcius for removal, dreamshapers for some really excellent draw (two mana for a 2/2 and two cards, hoo boy), paxes as a general good card (rest in pieces, thunderhorn), and whatever other Vetruvian and neutral goodstuff you want to stick in there. If Sajj heads the deck, then wildfire ankh gives you another threat and removal in one, and wind strikers and falciuses get better, or you could go Zirix and sneak a little dervish support or something in there, maybe some fireblaze obelysks to make cataclysmic fault scarier.
Lyonar golems aren’t bad, but I just don’t think they stand up. Warblades are really good if you’ve got a decent board and at least one golem, but if your board is poor they just aren’t that great, while dreamshapers only need to have the one golem out to generate high value. Sol pontiffs are good if you have even one other golem out, but fairly lame if not, while wind strikers don’t need any board to get full effect, but aren’t the greatest card, and wouldn’t be run except that golem metallurgist/dreamshaper/sirocco make them better. Finally, peacekeepers are too expensive to have no immediate effect, and so are just bad, while siroccos, after just a few golems, produce a not-easily solved problem for less mana, unless your opponent has mass removal. Dreamshapers and siroccos are what make Vetruvian golems worth running, and can give you value after you lose your board, while warblades and sol pontiffs are going to struggle to help you come back from an empty board.
