For the last 2 expansions blizzard has been giving gontrol warriors some cards that have ludicrous value and synergy, they are more numerous now than zoolocks and rush hunters seriously.
You see them at every tournament and every decent (and non-decent, if that exist, seriously, even if you are rank 25, its not shameful) rank, its just not funny when they delay you the whole game then drop Swagnaros, Alexstrasza, Sylvanas, Loatheb, Geddon, and 5 other legendaries depending on what they fancy.
