Power Tool Dragon

Per-phrase breakdown

• 1 Tuner + 1+ non-Tuner monstersOnce per turn: You can reveal 3 Equip Spells from your Deck, then your opponent randomly adds 1 of them to your hand, and shuffle the other cards into the Deck. (Ignition)
• If this card would be destroyed while equipped with an Equip Spell(s), you can send 1 of those cards to the GY instead. (Continuous)

Judge-facing facts

• Synchro Summoning requires 1 Tuner and 1 or more non-Tuner monsters.
• The effect to reveal 3 Equip Spells is an Ignition Effect.
• Adding the chosen card to the hand and shuffling the rest into the Deck occur simultaneously.
• After the opponent randomly selects one of the revealed cards, the chosen card is added to the hand and the remaining cards are shuffled into the Deck without revealing them to the opponent again.
• The effect to send an Equip Spell to the Graveyard instead of destruction is a Continuous Effect.
• If applying the substitution effect for battle destruction, decide to apply it during damage calculation and send the Equip Spell to the Graveyard after damage calculation.

Card-specific notes from database

• If an effect like 'Thunder King Rai-Oh' is applying when the Ignition Effect resolves, the effect is not applied and you do not reveal Equip Spells from the Deck. (YGOResources)
• If this card and its equipped Equip Spell(s) would be destroyed at the same time (e.g., by 'Judgment Dragon'), you cannot apply the substitution effect. (YGOResources)
• If a card like 'Macro Cosmos' is applying, you can still apply the substitution effect; the Equip Spell is banished instead, and this card is not destroyed. (YGOResources)
• If this card is equipped with 'Blast Sphere' and would be destroyed by its effect, you can send 'Blast Sphere' to the Graveyard instead; this card is not destroyed and you take no damage. (YGOResources)
• If this card would be destroyed by battle and you send its equipped 'Double Tool C&D' to the Graveyard instead, the effect of 'Double Tool C&D' to destroy the opponent's monster cannot be activated at the end of the Damage Step. (Konami neuron)
• If this card is treated as a Tuner, it can still be used as the named 'Power Tool Dragon' Synchro Material for 'Life Stream Dragon'. (YGOResources)
