Explosion Scientist, Bunta:
AUTO: [Counter Blast (1)] When this unit is placed on Vanguard Circle or Rear-guard Circle, if you have a «Great Nature» vanguard, you may pay the cost. If you do, put the top card of your deck into your damage zone, and at the beginning of your end phase, choose a card from your damage zone, return it to your deck, and shuffle your deck.
Big failure is the mother of big success! That must be it!
