Since in the B&R thread is often discussing skill, it would be interesting to know what the Sourcers think about skill-demanding cards in the format.

Note: What you're writing here is your personal opinion, so let's not devolve this thread into another B&R discussion.

Here's my personal list:

Most skill-intensive card of the format: Cabal Therapy (blind)
Most overrated card: Brainstorm
Most brainless card: Show and Tell (honorable mentions: Omniscience, Burn)
Most underrated card: Flickerwisp
