add 1 monster from your Deck to your hand with the same Type or Attribute as that monster, and the same Level as that monster's Rank, then place 1 card from your hand on top of the Deck, also for the rest of this turn after this card resolves, you cannot Special Summon from the Extra Deck, except Xyz Monsters
The Limited format runs decks at a 40-card minimum since players only get so many cards to choose from when building and they dont always have the cards they set their sights for
That sort of thing shouldn't be possible with modern legal cards
destroy that target, then, if this card was discarded from your hand to your GY by an opponents card effect, look at 1 random card in your opponents hand, then, if it was a monster, you can Special Summon it to your field
