Is this a good trade investment wise?
Hi im trading away my PSA 10 Umbreon & Darkrai TAG team and in return I will get a PSA 10 Ray Vmax, PSA 10 Mewtwo 151 Promo, Ascended, Surging Sparks, Prismatic, Black flair, Phantasmal Pokémon center ETB, Normal Prismatic ETB, 151 UPC, 151 ETB. It's a value for value trade I might have missed a couple things but it looks OK so far? I know the umbreon&Darkrai TAG team are low POP card but I feel the sealed stuff and the slabs will go up more in the future? I don't know if some will say it's an L trade because the tag team is kinda a grail? Appreciate some advice. Thanks all
