new awakening booster box One Piece OP05 of the Era – Each pack will come with 12 cards Digimon | [BT-08] New Awakening

While its age makes it hard to find this card in good condition, you won't find much of a deal if you opt for a worse condition, as this card's NM copies approach the $200 plateau

Best use case Buy sealed for the Triplet Beat product story and optionality

UR Ultra Rare Icejade Cenote Enion Cradle X SPELL Field When this card is activated: You can add 1 of your "Icejade" monsters that is banished or in your GY to your hand

But becareful of anaconda verte predaplant, you might end of giving them a free access to dragoon or DPE (or battle buttler for prank-kids)

I'll give you a few general ideas and a link to a great YouTube video that explains the combo(s) in detail
