The general idea of the deck is to get Lava Golem up and then crash into it with Swordswoman, perferably with equip items that nerf her and buff the Golem, though this can hypothetically be done with any high-ATK monster. With the massive amount of damage + Golem's auto-1000, a optimal field can be extremely dangerous.
Freed/Tomato/Spy act as your monster searchers, allowing you to get though the deck faster as well as stalling Golem if needed. Freed is also suprisingly quite good standalone given his spell immunity and draw effect, making him a issue that typically involves a waste of removal from the opponent. You don't really need to be too worried about general offence given Golem is universal field removal, though the side does consider that as I'll explain.
Kotetsu lets you get into your equips faster; Snatch Steal and Burial included alongside some beefy equips. 3x Trunade removes the issue of pesky traps alongside freeing the field if equips clog things up.
Traps are mostly general defence with a couple of extra burn stables thrown in in case of needing that little bit extra damage required if needed.
Game 2 changes things up by going into Panda Burn: almost always throws the opponent for a loop given the general long-game nature of the Golem strat, but it's a perfect fit for here so it doesn't harm the deck much. Wok helps for burn mirror and Kycoo/Big Bang/Nobleman help for Chaos variations.
