Cards you hate losing to?

What are some cards you hate losing to in Brawl?

I'll start \[\[Commandeer\]\]. I hate losing to bad cards and my god is this card awful, only working in one matchup, which is control and yet people keep playing it, hoping for that one Nicol Bolas to snag when 9 times out of 10 the card will be unplayable against Aggro or Midrange.

Obligatory bird hate with \[\[Nadu\]\] too because regardless of the change, it's a design mistake that should be entirely erase from the format and mtg as a whole.
