How can you stop Exodia?
Sending an Exodia card out-of-play is the most damaging and permanent way to stop Exodia. The fastest way to get that card back would be to use “Primal Seed” to put them back into your hand, but that requires cards that are banned in the Advanced Format in order to activate. The next fastest method would be to activate “Burial From a Different Dimension”, but that only puts cards into the Graveyard where you would have to use another card to add them to your hand.
