This is just something I cooked up after watching Educated Collins play around on the brawl with a control lock on stream.  His deck was more of an attrition deck but mine is a bit more focused on drawing fast and flexible combo finishers, but some games you will win on tempo and control.  I've got a pretty strong winrate with the deck, probably 60/70%+ while i was switching around cards.  Let me know if there is something you see that could be better, I didn't craft anything, just played with what I had.   

There are a couple combos you can use here.  The big one is Glinda Crowskin + Mechwarper + Ship's Cannon + Hungry Crab / Golakka Crawler.  It's an "infinite" (limited by APM) damage OTK that can be done at turn 9 at the latest but your [Hearthstone Card (galvinizer) Not Found]ticks can let you do it on turn 6-7.  You go Glinda, two mechwarpers, two cannons, crab kill something, then crab kill your own crabs over and over for cannon damage.

The deck can, and usually does, win in other ways too though.  [Hearthstone Card (Rafam's scheme) Not Found] for 5 imps with two cannons is 20 damage.  Zola can give you extras of whatever card you may need like cannons, or just extra crabs for removal.  

There are other interactions you can do like putting toxfin on your cannon and using it to clear a board. Sometimes you win with just glinda + mechwarper + clear their whole board with hungry crabs.  

Sacrificial Pact is probably the strongest class card in the format because you get a lot of healing and kill a thing for free, and since other classes can't tap you will usually win the resource game and you only NEED a big combo against other locks.  

Some tips when playing the deck

-Mulligan for crabs and librarian

-Try to hit combo pieces with Galvanizer

-Try to fit in taps while still fighting for board and tempo

-don't focus too much on the big combos but dont throw combo pieces on the board with no impact because everybody out here has crabs.
