DZ-SS16/Re07 Re Iron Claw Dragon, Gargurex

[AUTO]:When this unit is rode upon by "Iron Arm Dragon, Gargurex", look at the top five cards of your deck, choose up to one <Dinodragon> from among them, reveal it and put it into hand, and shuffle the deck.

[AUTO]:When this card is discarded from hand during your turn, or retired from (RC) by a card's ability during your turn, if you have a <Dinodragon> vanguard, put this card into soul.
