1 Tuner + 1 or more non-Tuner monsters Once per turn: You can reveal 3 Equip Spell Cards from your Deck, then your opponent randomly adds 1 of them to your hand, and you shuffle the rest back into your Deck. If this card would be destroyed while equipped with an Equip Spell Card(s), you can send 1 of those cards to the Graveyard instead.
Search effect is not accurate and can only be used when you have at least 3 Equip cards in your deck.
Protection effect costs 1 equip card attached to him.
Since Power Tool Dragon and Morphtronics share almost the same support you will most likely be using them together in a deck. In that case Morphtronic Scopen is an excellent way to get Power Tool Dragon out easily. Summon Scopen and then use his effect to special summon a level 4 Morphtronic monster from your hand and Synchro summon. Power Tool Dragon requires only generic monsters to Synchro summon so any monster with a special summoning event would be a good candidate. You can Synchro summon X-Saber Wayne and use his effect to special summon a level 2 Warrior Tuner from your hand to Synchro summon into Power Tool Dragon.
Here are some Equip cards that you can search with Power Tool Dragon and power him up. Gravity Blaster boosts your attack every turn and negates the effects of monsters Power Tool Dragon battles. Horn of the Unicorn and Axe of Despair give you a good attack boost and can be retrieved from the graveyard when Power Tool Dragon uses them as protection. Air Cracking the Storm allows Power Tool Dragon to make a second attack after destroying a monster. Break! Draw! gives you an additional draw every time Power Tool Dragon destroys an opponent's monster battle. Mage Power gives you an increasing attack boost when you control multiple Spell/Trap cards on the field. Double Tool C&D gives you a 1000 attack boost and negates the effect of the monster you battle.
Synchro Power Tool Dragon and a level 1 tuner to summon this monster. When summoned Life Stream Dragon replenishes your LP back to 4000. You can then beatdown your opponent with his 2900 attack while he can be protected from destruction by banishing Equip cards from your graveyard.
Use these skills to support your Power Tool Dragon. Twins Together adds Double Ripple from your deck to hand which is a good way to summon Power Tool Dragon along with Ancient Fairy Dragon. Spell Recycle: Equipment can be used to recycle Equip cards in your graveyard and add them to the deck for Power Tool Dragon to search out again. Equipment Restock is a more powerful version of Spell Recycle: Equipment which retrieves an Equip card from your graveyard to your hand and then and then retrieves another to your deck but can only be used once per Duel.
