Not that PSA has been strict with upcharges, but it does provide some peace of mind when sending in higher-end cards
In many ways, I feel like that is the proper way to write a spin-off
Souleating Oviraptor X DARK Level 4 [ Dinosaur / Effect ] ATK 1800 DEF 500 If this card is Normal or Special Summoned: You can take 1 Dinosaur monster from your Deck, and either add it to your hand or send it to the GY
Once per turn, you can select 1 face-up monster your opponent controls, and equip it to this card
At worst, this is a 5 mana, draw multiple cards spell, essentially, assuming you immediately kill it for its -3 ability
You'll rarely want to summon this card to the field, since it has zero attack or defence
