Titan Roaches

Hello everyone! just crafted the 2 crowns i was missing and decided to try brewing some clockroaches lists....damn these things are so much fun! titan is required cause we have 0 defense against fliers,whispering wind is used to search for the roaches and the crowns and that's pretty much it
any suggestions are greatly appreciated,i'd like to try and make this deck a bit more competitive =D

P.S : i cut the 4 cirso out cause i realized they were just too slow,and at that point of the game you already want to be playing big roaches,so i realized he was just superflous
