Agatha's Soul Cauldron saw a surge in play because it enables graveyard-centric combos and counter synergies. Standard decks that exploit +1/+1 counters or activated abilities can use it to recycle creatures and share abilities in creative ways. It also offers incidental graveyard hate, which is valuable when reanimation and flashback effects are popular. The card's combo potential has kept it in the spotlight since release.
