Survive early turns with 1:1 trades or by using your health as a resource. Despite the nerf, you still want to find a Bol'shoy Constructor to give yourself flexibility in what you can play, as this deck feels mana restrictive in early- to mid-game. It can also be used to protect other artifacts (it really only needs to survive a few turns, and soaking damage that won't break it is fine). Just be aware of how and when you will want RR (early, usually turn 3) and GGG (late, ideally 6 or 7). It's hand-dependent, obviously, but it's your goal.
Burn your lategame bombs early. If you don't see them again, so be it. You need to survive. You can also potentially draw into your one Pseudonomicon to have a nice toolbox of options. Just don't count on it (1:40 = real odds to overcome).
We run 17 artifacts in here so the odds of finding one with a forgeling are high, and the odds of getting another to spawn a forgeling are also high. Fun fact, each time you attack with Vestai Virago, you will get an additional forgeling added to your hand, so never really feel bad about burning forgelings for extra mana.
