Mulligans
A June edition of my Uberfun Mech Mage.
Big minions, discounted to unbelievable value, supported by Khadgar and a mech package.
This is so much fun to play, and quite effective too. Key win conditions are who overwhelm with a big mech, Janalai into double Ragnaros or CC on a giggling inventor/Mech whelp w/Khadgar. Other fun cards are Da Undatakah and Kalecgos though neither are essential, both are quite good as 1 drops.
Book of spectres is best saved until after you play LPG (as the amount of magnetic mechs you can potentially pull makes this a consistent play) and losing LPG to a BoS, although not necessarily an instant concede, it will set you back in the late game.
Finally Baleful Banker should obviously be saved for Khadgar.
When Mulliganing, absolutely keep Khadgar, Janalai and Conjurors calling (Hex Lord Malacras makes these good to keep).
Otherwise, have fun watching your opponents squirm as you summon a GI with 4 annoy-o bots then use CC next turn on the GI for 4 more 7 drops!
