Generation Shift

Destroy 1 face-up monster on your side of the field. Add 1 card from your Deck to your hand with the same name as the destroyed card.

These are 2 general uses of GenShift. Any card that you need to be sent to the grave, or if you need additional cards of the same type in grave, will become more useful with GenShift. GenShift will send a monster to the grave and get the same type of monster from your deck. It's a good escape from lightning vortex, and extreamly useful way to get pieces of exodia by usining it on emissary of the afterlife. Great to use on manticore of darkness. If you use GenShift on it, you will have another manticore of darkness in your hand, and you can send that to the grave to revive the first one, then send another card to the grave to revive the second one. By using GenShift on manticore of darkness, you will have 2 manticores of darkness on the field. Add card of safe return to that, and you will have plenty of cards to revive it with.
