Jewel of N'zoth is a popular inclusion, but after many games, I found the spell tends to sit in the hand against fast matchups and against even the slower decks you often do not need that huge reload on the board to close out games. I replaced Jewels with Plagued Protodrake. Making the pool for Maxima better and Protodrake can be pulled from the hand with Vol'jin where Jewel of N'zoth cannot. With no Jewels that allows you to play Ursatrons to tutor your mechs (Oblivitron and Tonks). Octosari is my replacement of Jewel for the matchups where value is needed. If you thought Ultimate Infestation was a good card, just wait til you fire a massive Octosari from Maxima. Secrets can be varied depending on popular matchups. VS the popular weapon rogue i have been rotating a misdirection for freezing trap. can block a big weapon swing in the late game where an explosive trap would not do much. These situations can be easy to set up because all secrets are cast from hand you can decide the timing of your secrets.
