I disagree with that. While Fated Infatuation gives you a "permanent token", it won't do more blocking than your Mirror Mockery token. And Mirror Mockery can produce massive amounts of tokens with Master of Waves, where Fated Infatuation only produces tokens once.

I was just thinking about building this exact deck almost. Great minds...I would however, mainly for curve purposes, replace one or both of the Vaporkins with Vortex Elementals. you get an elemental out with the same amount of devotion and if you play it when you would have played the vaporkin you also get a chance to deter an attack or deal with an early dash threat.

Hmmm... I like the idea of an Elemental Tribal and Blue devotion deck. I think what you are really missing are some 1-drops! The only good blue 1-drops right now are: Dakra Mystic, Gudul Lurker, Hypnotic Siren, Sidisi's Faithful, and Vortex Elemental. If you really want to keep with the elemental theme, then I would add some Vortex Elementals, but they aren't really that good. I would just not focus on the elemental theme and add in some Aggresive 1-drops that can't be blocked or draw you cards. Besides that, nice deck! I love mono-blue devotion.

Great deck. I always have a hard time making standard any good. But you seem to have done it. :)

Thank you theGentlemanSeal! Sorry I responded to your comment so late, but I was away at sleepaway camp!
