Astral Phasing

Description
Give a friendly minion +5 Health and Flying.

Strategies

 * Astral Phasing can be played as a tech card against enemy soft removal that repositions minions. This includes cards such as Juxtaposition, Daemonic Lure and Hearth-Sister. Still, this card rarely sees play: 3 mana for such a weak buff (that is, it does not bestow attack) is not optimal.
 * It offers good synergies with Thunderhorn, Wild Tahr or other Frenzy minions because it allows these minions to surprise attack with possible devastating effect.

Gauntlet
In Gauntlet it can be drafted as a kind of removal or just to give an important minion a lot more resilience and mobility.
