It's reactive and continuous, and while it doesn't negate graveyard effects, it can weaken the opponent's overall grave power a lot making it a good side option against a number of decks.
 
3/5

Earthshattering Event...appropriate picture at the very least.  This is a fun little piece of tech I think.  If a card (or cards) is (are) sent to the Graveyard, target a card in either Graveyard, and shuffle that target back into the respective Deck.  Furthermore, neither player can send cards from the Deck to the Graveyard for the rest of the turn.  This is a thinking mans card.  Use it for you, dump what you need to, and recycle something you'd like, and while it can suck not being able to dump the rest of the turn, it's not as though you don't get to at all.  Or recycle something of your opponent's you know they need in the Graveyard.  Ideally, this process hurts them more than you.  I suppose this is just stalling to a degree if you're using it against your opponent, but I think it's more disruptive and effective than stalling.

Hello Pojo Fans,
 
Today we're shaking things up with Earthshattering Event. A Continuous Spell isn't normally a good card unless it does something fantastic that can change the tempo of the game in your favor, as anything that stays on the field is a target for destruction.
 
If you send a card to the grave from your deck, you can target a card in either grave and shuffle it back into the players deck, however, you can't send card(s) from your deck to the grave for the rest of the turn. This could have a tremendous impact in the meta in slowing down the Tier 1 decks like Burning Abyss and Shaddoll. Lightsworn get crippled by this, only being able to mill for one monster during their End Phase. In a mirror match of Tier 1 decks, this card could slow your opponent for a turn or two, giving you an opening to take advantage. Even if it only lasts one turn, you can use that turn to send something to your grave, then either take away a resource from your opponent, or put something back into your deck that you need. This doesn't specify the main deck, so recycling Xyz, Fusion, and Synchro monsters is also an option. Gone through a spell/trap you love to play? Recycle it after sending a card to the grave.
 
While it may not last for very long, it's effect will persist if destroyed by something being sent to the graveyard from your deck (Shaddoll Dragon). 
 
Advanced-3/5- It has potential to be used better in decks that don't send to the grave vs decks that do
