Not really, I've reached KoG last month with copies of floodgate and canadia instead of econ. Econ is too mainstream since people just copy paste stuff. Lmao
i didnt use econ either in my deck.. reached kog too. econ not fast enough and with fur hire you need more backrow removal than minion removal cause your minions always overwhelm the enemy's.. you need to destroy their protection
econ was best for mirror matches to prevent your opponent from making plays or advancing your own. combos well with mayhem. fur hires really unaffected.
