If we were just looking at the cumulative upkeep, Juju Bubble would not be a bad card
Instead of one player having to read out each item's description and their cost, you can just laid out these cards and let players pick what they want to get
The player can either discard a Monster to shuffle all the opponents own back into their deck, send one of their controlled Spells or Traps to the Graveyard to send all of the opponents back to the deck, or mill a card to shuffle the opponents whole Graveyard back into their deck
Name the exact item, state the quantity or stack size, note the rarity tier, mention how in-demand it is, and confirm how it will be delivered and how long that takes
The archetype has good Fusion monsters, such as Tearlaments Kitkallos, which is the archetype's card seeker, but also has the effect of sending cards to the graveyard
