The Advocates’ dedication to the land doesn’t extend to supporting each other, though. The line of rules text that says “Sylvan Advocate gains +2/+2” actually means “This creature, which happens to be named Sylvan Advocate, gets +2/+2,” and not any other creature that shares the same name. To work otherwise, it would have to say “…creatures you control named Sylvan Advocate…”. Therefore, if you have two Advocates, both of them will be 4/5s, even though a 2/3 land creature you control (like Shambling Vent) will be pumped up to a 6/7.
