Auction house premium: Heritage Auctions and PWCC command 10-20% premiums over eBay for high-end Base Set cards due to authentication guarantees and collector audience

Dont endorse those selling sealed product at double or triple the MSRP

This means that if you include Radiant Greninja ASR 46, you cant also include Radiant Gardevoir LOR 69 in your deck

In some cases, that might be very literal, with your Pokemon being weak to attacks of other types

The gradually increasing price reflects this trend of dwindling supply, although fans can still get a hold of the card for even cheaper for the time being by keeping an eye on listings
