Startegy

• Have 1 trap set (not 2, because of Xing Zhen Hu) behind Labyrinth Wall to counteract Bonz’s Tribute to The Doomed. With 5 traps you have a good chance of opening with 1. You may want to stall on summoning wall with your skill until you have a trap.
• Earthshattering Event, Pot of Benevolence, and Shard of Greed are used to counteract Bonz milling through the effect of Gozuki. Prioritize Skull Servant to return to the deck. Don’t play the second Earthshattering Event until you use one of your traps & the first is destroyed.
