In the game of Yu-Gi-Oh! Is there a difference between discarding a card and destroying a card from the hand?
So I have a dinosaur Yu-Gi-Oh! deck, and I am wondering about the effect of Fossil Excavation...
[Activate this card by discarding 1 card, then target 1 Dinosaur-Type monster in your Graveyard; Special Summon that target. Negate the effects of that monster on the field. When this card leaves the field, destroy that monster. When that monster is destroyed, destroy this card.]
...in combination with either Babycerasaurus
[If this card is destroyed by a card effect and sent to the Graveyard: Special Summon 1 Level 4 or lower Dinosaur-Type monster from your Deck.]
...and/or Petiteranodon?
[If this card is destroyed by a card effect and sent to the Graveyard: Special Summon 1 Level 4 or higher Dinosaur-Type monster from your Deck, but it cannot attack this turn.]
Also, is there a difference between a discard and destroying a card from the hand?
