Temur needed a creature like this, and it got one. Abzan didn’t need a creature like this, but it got one anyway. Hardened Scales didn’t need this, either, but popping an extra +1/+1 counter on him seems ridiculous. It’s pretty easy to get the three colors of mana, with Rattleclaw Mystic hanging around, and the newly spoiled Beastcaller Expert able to give an off-color fourth color of mana to benefit him. What Standard was losing with Polukranos, World Eater, it’s pretty much getting back with Woodland Wanderer - although losing the Monstrosity ability is not irrelevant.
This appears to be one of the best Standard-playable creatures from Battle for Zendikar. What do you all think?
