Spirt of the Eldar Lizard is used so often because its ridiculously stat efficient, cheap, with lots of regen in lane for free. Of course a BT or BoTRK is better, but they are also ~1200 more, which in and of itself is a Sheen right there. Tear helps his mana probelms, he can stack it fast, he gets free AD, and it makes his poke strong as hell.
