Isn't this the premade deck The Scrap Heap?

Nice deck Flux, hovering around rank 4 with it, but all these pesky murloc / token druids are hard matchups, maybe you have different techs? I want to sub Shaw in, but I dunno, feels like i-win more card tbh, thoughts?

Decided to swap Bomb Toss with a Cybertech Chip and Boom-Zooka, actually getting good results out of them.

I have all of the cards which I just crafted except Zul'jin, Ziliax and 2 nine lives, planing to craft them all in april, which ones first?

I'd start with Zul'jin, unless you're playing other decks that need Zilliax since he's so strong. Nine Lives for last.

Any replacement for zuljin?

This is a great deck. You can beat almost every deck on the ladder. It struggles against token druid unless you get really lucky with your starting hand. I went from rank 6 to rank 3. Here's the proof:

Hopefully you can have as much fun as I had when I played this deck!

I found mecharoo to be underwhelming and I subbed in 2 Shimmerfly, not a mech but is a deathrattle and generates a spell for Zuljin, also Safeguard is  a good choice for this deck as well, this is a fun deck to play ty for sharing : )

Weak minions, doesn't look impactful. 
Beast Hunter looks better

Is Obliviotron relevant ?

no not at all. it makes no sense in this list with all the crap deathrattles and mechs,

He can be rly strong. He gives you a lot of value

For this kind of deck, not really. The card works better with a deck that has highly impactful deathrattles but even with that, the stats on the card are SO BAD for a legendary that most will not run it for that reason.

That's funny because a lot of streamers played it and said it was actually a great card in a lot of match-ups.  Some consider it to be one of the set sleeper and I personally find this card having a big impact in games since it's tough to deal with.
