Thanks for the advice. I’ve changed a couple of things; I’ve taken out a pact and put an applebaum in, I’ve put 2 voodoo dolls in which combo well with both pact and mortal coil. I’ve removed the extra cataclysm and blood bloom (wasted spaces in the deck). What do you think?

Just an idea for a deck that could work for Mecha’Thun, I would appreciate any feedback on the deck list. Also it’s my first deck that I’ve built on this site so I apologise for how badly it’s formatted 🙂
