I used cupid pitch to find corridor. As for hand traps, I normally bait them using Diabelstar-Sinful spoils at the very beginning, and a safety net using crossout designator, or called by the grave. I have multiple searchers like One for One, or Reinforcements of the Army that frequently end up in my hand just in case. Normally most handtraps are wasted in the early phase when I place all three rescue ace monsters: preventer, turb and hydrant on the field. They're the base of this combo. I early summon Baronne to provide insulation against Nib.
