From March 2nd:
“Hello
We currently do not grade Marvel cards.
This is what we grade. CGC Trading Cards accepts virtually all Pokémon TCG and Magic: The Gathering cards as well as other popular trading card games, including:
Digimon
Dragon Ball Super
Final Fantasy

CGC Trading Cards also accepts Gamma play test Magic cards, "Artist's Alterations" (altered by the artist of the card) and "Artistic Alterations" (altered by anyone in an artful way). Artistically altered cards are generally encapsulated with the Qualified (Green) Label.
At this time, CGC Trading Cards does not accept the following card types:
Cards larger than standard playing sizes.
Non-TCG Pokémon cards, such as those made by Topps.
Cards other than those listed above.”
