War Rock deck, using minimal non-engine, heavily focused on the battle phase. So here's the thing. Archetype bad. Deck bad. But it can be a lil fun. Pyrite Knight is an earth warrior and an additional enabler to vomit warriors from hand to the field like Mountain, and though the token is annoying, it is usually removed easily. Slayer is a little booster in case a competent deck is encountered. Generally stats are good in both ATK & DEF, so Magnum Shield is usable, and how often can one say that.
Regarding the alts, Heroic Challengers can be used an engine, Morganites and especially the the red one are useful but clash with a couple of effects like Gactos & Rookie, Cyclone for more non-engine, Reinforcement is more swarming but low-level, The A. Forces is an ATK boost that doesn't require attacks to be made (lawd they so bad), Ordeal clashes with Extrav and probably doesn't offer much anyway, the traps are pointless since going 2nd is the preferred way.
