"Recycling Batteries", if retrieved, allows you to place two Thunder-Type monsters with ATK of 1500 or less in your hand. "Magical Stone Excavation" will let you discard monsters you may not be able to use, and still replenish your hand-size the same amount. This works well in "Batteryman" Decks.
This card is a good alternative to "Spell Reclamation", as the cost is essentially the same, however you can use the Spell Card on the same turn you get it.
This card is also simply a more powerful version of "Spell Reproduction", being that it is less specific.
This card works well in a "Crystal Beast" Deck. Activate "Crystal Blessing", then activate this card discarding 2 "Crystal Beasts" choosing "Crystal Blessing". You can use again "Crystal Blessing" you returned to your hand targeting the 2 cards discarded before and you are ready to use "Crystal Abundance".
This card can be used to discard targets for "Infernity Necromancer", allowing you to ensure a "handless combo" and build field presence.
You can use this card to reuse "Rekindling" and send "Flamvell" monsters to the Graveyard.
Set this card and a revival Spell Card ("Swing of Memories", "Monster Reborn", etc.), then activate "Card Destruction" to send 2 high level monsters to the graveyard and draw two more cards (the cost for this card). Now you can use the rebirth spell twice in a row.
