Mulligans
The 9th deck out of my 10 theorycrafts, Implock looks to be one of the strongest new archtypes, if not the strongest new archtype. Honestly impending catastrophe could be THE strongest draw engine in standard and all of the cards just seem to work. Draw a big hand off of an aggressive token start to summon a big dark alley pact which can then be resummoned by rafaam (yes, it’s an imp). Lady Darkvein also copies your Dark Alley Pactg or your impending catastrophes. I think the deck has enough draw without Tamsin, so I opted for a little more aggressive cards like shady bartender and demonic assault.
