ultra moon booster box Pokemon TCG Japanese Sun & Sun (SM5s) – PokeWayne Booster pack from SM5M Ultra Moon (Japanese only) Pokemon Ultra Moon Booster Box

With the reprinting of the card in Standard for the first time in years, it gives the Elves a chance to shine with their fantastic new card

If an "Abyss Script" Spell Card or effect is activated: You can Special Summon 1 Level 4 or lower "Abyss Actor" Pendulum Monster from your Deck, but return it to the hand during the End Phase

EDIT: A new and more likely theory has presented itself for Grey stamps in this post by @pokemonrevolution

Since "Indiora Doom Volt" was sent to the Graveyard, its effect activates, letting him return it to his hand and Special Summon the three "Vijam" (0/0 each) underneath it

The padded leatherette cover, complete with premium colored stitching, is built for durability and designed to maintain its professional appearance with regular use
