Basically what Dom said. The mana cost in addition to the discarding kills it for me. Speaking of "lower powered" recursion in blue, I'm slowly realizing that this little gem is actually not nearly as much of a whiff as I thought (and yes I know other people might have realized this beforehand somewhere else in this forum):
This seems especially true for me as I start to fully realize that my particular format is lower-powered than I thought at first.
EDIT: Though it still looks a little silly next to Snapcaster mage. But that's ok. Snappy was a little bit too pushed, if you know what I mean, and he still scales with format power. Archaeomancer also allows you to split up the cost, which is nice for something like Planar Outburst that you might not have enough to snap-use, but can recur after a duress, and cast on curve next turn.
