Huatli feels at home in just about any Naya deck
This would be a fantastic choice for any blue player that wants to see what life is like on the other side, but isnt quite ready to give up the fairer color
Its possible that some time in the future of Standard the mana dries up and we see mono-colorless or close to it pop up, or a single card gets printed that makes a deck in an Eternal format tighten up its mana, but odds are until more sets are printed with this mechanic, mono-colorless isnt much more viable than it is now
Those are the three big boxes to check off for most effects, and this gives you all three if you need it
From then on, Extort will still trigger on every spell, but we will always ignore it
