I had a long and exhaustive reply all typed out, but I accidentally refreshed and erased it all.
Since I am faaar too lazy to type all of it again, I will merely point out the factual inaccuracies in the post. The ability to deal spell damage, referenced in Psion, Phase Dragon, and Shard of Wisdom, is psion, not psionist. Phase Dragon stats are 8/6|10/6, not 8/6|8/8.
More of a minor quibble, but
The problem I have with this card is that it targets immaterial creatures, which no card should do in my opinion, but this thread isn’t about my opinion.
Are you sure, are you
absolutely sure that this thread isn't about your opinion?
Anyway, generally speaking, I disagree with your analysis towards Aether cards and Aether in general, but I don't feel like typing out why again.
