I was running a similar deck. I think yours could be better if you removed the tech cards. The meta is a mess right now, so tech-ing is not very reliable. In dozens of matches now I have run across one pirate deck and no murloc decks, so I think you could replace those with something better. Add either back in if the meta dictates once it settles. I'd add another stitched tracker. And maybe 2x fiery bat or cat trick for more cheap minions.
Agreed! Imagine dual Arfus draw, with two Play Dead draws.
Below is the deck I ran yesterday, ended up with the longest win streak I've had in a long time (10-1). Broke into the Top 10 with it.
Play Dead just combos so well with different early, mid options. And Bearshark is a much better combo with Houndmaster than Animal Companion was.
