I don't see anything wrong with solid cards that are played in certain deck types. I like cards which flirt with overpowered-ness without quite crossing that threshold. It's exciting. Also playing Stalagg as a counter is actually very good providing you kill Feugen before or on the turn you play Stalagg. Your opponent has gotten a 4/7, but you've gotten a 7/4 plus whatever crazy amount of stats Thaddius is.
