Collector's Notes: The Cosmos Reverse Holofoil looks very similar to the standard Reverse Holofoil but features a shimming galactic outer space pattern within the holofoil which does not extend into the artwork of the card.
As of this writing, the 4 Cosmos Reverse Holofoils were promotional cards included with a special 5-pack of collectible "151" tins exclusive to the retailer Costco.
