If you think you're holding a truly valuable Pokmon card, your first port of call is to get it protected by placing it in a thin, soft-plastic sleeve, then into a protective, hard-plastic 'toploader' case
Variants are free and unlimited
Pokmon fan and eBay seller Tomoya Ohno is putting the starting bid for the card at $480,000
Four mana is still a lot, however
Where the card shines, though, is in its overload ability, which lets you cast the card for a higher cost and extends its effect from a single creature to each one you don't control
This is an incredibly strong effect that makes excellent use of powerful lands like Valakut, the Molten Pinnacle
