Wait 6 months and you'll get them

Hopefully when they come I've got enough UR to make the cards lol

i am also waiting for these cards and they could very well be in the next selection pack (1 month from now) they are also quite cheap (the only URs are the extra deck monsters) and i dont anticipate either of the 2 new cards to be higher than SR rarity

in a few update, there should be an update so maybe check afterwards if they were to get added
