One of elves strengths is being wasteland proof. Very rarely do I care if my creature gets countered. Removal is more a problem than counters for elves. The only creature that I typically need to resolve is scavenging ooze, not an elf.
In fact, I believe the non creature spells are more important to resolve:GSZ, Glimpse of Nature, and Natural Order. However, if counterbalance ever became a DTB again than this land would be a staple in at the least our sideboards.
