"A golem made by a modern magus couldn't possibly last even two hits from you, not even if he spent his entire life working on it."

There are exceptions, of course. The world is a big place and it is possible that a magus exists who can create golems on par with Servants. However, it does not seem likely that one would exist among the Yggdmillennia. The best golemancer within their clan is Roche Frain Yggdmillennia and as good as his golems are, they will not be able to withstand even one of Saber's swings.
