Use this card to search not only "Karakuri" monsters, but also spells and traps. For instance, if your opponent controls a monster with 0 DEF and high ATK, you can summon this card, search out "Karakuri Showdown Castle", and attack their monster, using the "Castle's" effect to switch their monster to defense position.
Use this card and "Ultimate Offering" to search out other copies of itself, quickly filling your field with monsters to attack with or perform a Synchro Summon with.
If you're using this, another possibility is to normal summon this card and use its effect to search out a "Karakuri Cash Cache", then target it with "Cash Cache" to search out another Merchant. Use "Cash Cache's" effect to search out another "Merchant" and repeat, then summon the last "Merchant" and use its effect to grab "Karakuri Ninja mdl 7749 "Nanashick"". Summon "Nanashick" for an immediate draw of two cards, or hold onto it and use a Synchro chain with "Karakuri Shogun mdl 00 "Burei"" or "Karakuri Steel Shogun mdl 00X "Bureido"" to get additional defense-position Karakuri onto the field to increase your drawing potential.
