This card can be searched by Dogu, Single Purchase, Temple of the Kings, Transmodify, Mimiclay, Sangan, "Rescue Ferret", Chaofeng, Phantom of the Yang Zing, Hot Red Dragon Archfiend Bane, Serpentine Princess, Vampire Dragon, UFO Turtle, Masked Dragon, Ninjitsu Art of Super-Transformation, Dragonic Guard, Draconnection, Dragunity Corsesca, Dragunity Knight - Gae Dearg, Hieratic Dragon King of Atum, "Soldier Dragon", and another "Dread Dragon".
Special Summon this card with Masked Dragon. Conveniently, this card searches out "Masked Dragon".
This card is good for Dragunity and/or Cyberdarks.
The advantage of this card over "Masked Dragon" is that it can search out certain dragons that have more than 1500 ATK such as Hunter Dragon. However, one disadvantage will be that this card will only add the searched card to your hand whereas "Masked Dragon" can Special Summon the card you choose.
Along with other monsters, you can search for this card as well.
If you have Cards of Consonance in hand, and "Dread Dragon" gets destroyed by battle, you can search for "White Stone of Legend"/Flamvell Guard, and then use "Cards of Consonance" to discard the Tuner and draw two cards. If using "White Stone", you can then add Blue-Eyes White Dragon to your hand and use Trade-In to discard him to draw two more.
