Retrieves 1 Spell card from your Graveyard to your hand.
Costly to use as it requires 2 cards to be discarded.
Currently due to the vast options of Spell/Trap cards, we don’t see much uses for Magical Stone Excavation, aside from bringing back limited edition Spell cards such as Swing of Memories, Burst Stream of Destruction, Dark Magic Attack etc.
Another downside of this card is the steep cost of requiring 2 cards to be discarded in order to activate its effect, which greatly effects your hand numbers.
If you have Swing of Memories in your Graveyard, you can use Magical Stone Excavation to retrieve it from your Graveyard, discard 2 monsters such as Darkstorm Dragon or Phoenix Gearfried, use Swing of Memories to bring 1 of these discarded monsters back to the field, perform your attacks, and during the End Phase when your monster is destroyed, use A Deal with Dark Ruler to bring out Berserk Dragon from your deck to maintain field presence.
This card will mainly come useful when/if we get Morphing Jar and Book of Moon to use with A/D Changer, A Feather of The phoenix and the other Empty Jar card list. However, I don't see Duel Links getting Morphing Jar in the near future.
