Control Mech Paladn

Principal Combo: Archmage Vargoth + Kangor's Endless Army
-That’s a 11-mana combo, so we need reduce the cost of one of these to do it, for this the decks only have 6-cost minion or less, then you can play Prismatic Lens and draw Kangor's Endless Army reduced (If Prismatic Lens draw other Prismatic Lens, just do it again)

More Value?: Arcane Dynamo into Kangor's Endless Army
Paladin doesn’t have too much spells that cost more than 5, so Arcane Dynamo probably can discover Kangor's Endless Army (8 Spells with 3 discovers, ~37% chance with anyone)

What magnetize?: Galvanizer, Weaponized Pinata and Mechano-Egg
Any time you play Galvanizer, you must magtize something to it, because resurrect a 1/2 is horrible. Resurrect Weaponized Pinata or Mechano-Egg it’s okey, but are another good cards to magnetize.

Draw cards?: Acolyte of Pain, Prismatic Lens and Witchwood Piper
Acolyte of Pain can be buffed with Glowstone Technician, so you can draw more. Prismatic Lens is so important for the combo, but is another draw card at last. And Witchwood Piper always draw Galvanizer if you don’t draw it before.

Why not SN1P-SN4P? The deathrattle. Summon 1/1 Microbots destroy our combo. 

Good Card to put: If you take off Witchwood Piper, you can put Lorewalker Cho, because you don’t have spells (Except the combo’s one).
