I'm trying to make a deck with this engine but does have some defensive abilities. And my choice is gonna be lavals just for fun.It is a F2P account so only 1 structure deck but the half price packs will help.
Extra Deck: Shooting star, Stardust, junk archer, Junk warrior 2x, Stennon, laval Dragon
Deck have consistency due to Warrior returning alive adding converter or a cannonbut sadly quickdraw and Jet does not synergies with handmaiden since it can miss timing.
Conduction feild + Dustflame is a good turn 1 indeed but that's 2 specific cards in an almost 30 card deck. Warrior returning alive will still not solve the turn 1 weakness of then synchron engine since all you can do is summon stardust or shooting star.
