I discovered this little gem online and decided to give it a whirl. I went 6-1 with it only losing to a Warlock deck (shocking..). Regardless it’s very cool, and you can quickly overwhelm your opponent right out of the gate. As far as mulligan tips go, try to get a Secret Keeper in your opening hand along with some of the 2 drop Secrets in order to pump it. You can also look for an Alleycat and a Cloaked Huntress. The Alleycat puts instant pressure on your opponent and on T3 the Huntress comes out and your secrets are now free. It’s a very synergistic deck that can put up a fight against anything out there, besides Warlock apparently. I definitely recommend you try this one out and let us know what you think.
