This is the second Huatli planeswalker showcased in the Ixalan block, the first one being released in September 2017. This one is focused around its second ability that can signficantly buff your creatures.
The ultimate ability is good, but it's nothing to write home about. If you can get it, good -- if not, no problem. Huatli will do nothing without creatures, so decks that utilize many creatures will win the most.
