General MulligansThe mechs are top priority because your combo must have an extra one of each, and duplicating them with Hex Lord Malacrass can save you time. Extra Youthful Brewmasters may be used to bounce the Galvanizer back to your hand in case you have all the Clockwork Automatons in hand, but not all the Galvanizers.
This is a one-turn-kill mage deck consisting exclusively of cards that are in the standard set for Year of the Dragon.
You can speed the replication process if you use Archmage Arugal (preferably in combination with Arcane Intellect) , or if one or both mechs were in your in your starting hand and you play Hex Lord Malacrass.
Subject 9 gets you closer to the cards in your combo by thinning your deck. It replaces two Novice Engineer and two Loot Hoarder, giving you up to five secrets that you can play without timing constraints, and with tempo if you have a Kirin Tor Mage in your hand. This gives you better value and less crowded hand problems than the draw cards in some other combo decks often create.
