Drawing 2 cards per turn on average would be utterly fantastic, but as long as it averages 1 card it's still good in just about any Mono White deck
As you can see below, the main deck has exactly 53 cards
Despite everything, most of Joeys cards are more iconic than viable in the real TCG
Card Text 2 [Inherited Effect] Retaliation (When only this Digimon is deleted in battle, delete the Digimon it battled.) BT17-064 C Digimon Lv.4 Pipismon Color Purple Blue Cost 5 DP 5000 Digivolve Cost 1 PurpleBlue 3 from Lv.3 Form Armor Form Attribute Free Type Mutant Card Text 1 [Special Digivolution Condition] [Digivolve] [Patamon]: Cost 2 [Effect] Armor Purge [When Digivolving] Trash the bottom 2 digivolution cards of 1 of your opponent's Digimon
But those are difficult to find given their popularity. While a grade 3 good condition first edition Lugia can go for $40, higher graded ones can go for several thousand dollars
It'd function like a much more limited Captain Sisay, both in color identity and scope of what you can fetch
