One of the problems running with Agro decks is card draw. I tried to alleviate that with the inclusion of Salhet's Pride and Crystology. Otherwise the general game plan is to buff your cards in your hand with Grimestreet Outfitter, Smugglers's Run, or Glowstone Technician. Magnetic Effects make your mechs harder to kill and provide extra damage. The inclusion of Coppertail Imposter may look surprising, but since there is so many Magnetic cards in the deck, it alleviates some chances of it dying at the cost of some face damage.
Side note, can I say that I love that this deck makes use of multiple sets of expansions. I think that very cool.
