I was introduced to this card a while back and honestly I think it seems quite interesting: Aethermage's Touch. I'm considering it in a homebrew OmniTell I've been working on for a while now because:

  • You get essentially a surprise blocker (when cast on opponent's turn) and then a free swing with something like Emrakul
  • It doesn't seem too CMC-expensive at 2UW
  • you get the creature back into your hand at the end of your turn, allowing you to then cast it with Omnscience at some point
  • you potentially can remove cards you don't want/need to the bottom of the deck


However, looking at other commentary on this card, the community seems kinda split on it. Gatherer's comments seem to show that people don't realize it's an instant (most of the issues seem to be focused on summoning sickness which isn't a problem if it's played on a turn other your own), but why doesn't this card see more play otherwise?
