This card's searching effect also activates if it is equipped to a monster. As such, it can be activated by using the equipped monster as Synchro or Xyz Material or in monsters that Tribute themselves to activate their effects, such as "Superheavy Samurai Flutist", "Thief", "Transporter" etc.
Provided "Superheavy Samurai Helper" is in the Graveyard, it is possible to activate this card's effect at least 3 times during the opponent's Battle Phase, thinning the Deck and possibly blocking an OTK and enduring until the next turn:
When a second opponent's monster attack directly, use the effect of "Helper" to Special Summon this card.
If the opponent choose to destroy this card again, its effect will trigger once more; this time, search "Superheavy Samurai Prepped Defense" and immediately activate "Soulbeads", Special Summoning this card.
If the opponent attack this card, the battle damage will trigger the effect of "Prepped Defense", which in turn will be indestructible for the rest of that turn.
