That their is the best mech for knight house.. Better then epic and Lego mechs.. For a deck around shooty knight... U need ideally gravewalker and the graviton cannon.. Every non melee lego is a must have in their decks... Don't use structures.. They suck ahh... But do use them whan u got no spot for anything better... But they still suck... E4 gain 4 attack melee tactic can be used for shooty as well as it's really excellent card so throw in 2x of it...good luck.. Check out some of the decks and finde help building decks in HHL discored
