First off, the deck was incredibly weak on card draw: I had Esper Sentinel, Strength-Testing Hammer with some ways to tutor it, and thats basically it
Wonder (Odyssey/Torment/Judgment) Odyssey Block dealt heavily in the graveyard, between threshold, flashback, madness (discarding cards) and the Judgment Incarnations
There are eleven in total: Alolan Rattata Alolan Raticate Alolan Meowth Alolan Persian Alolan Grimer Alolan Muk ex Absol Trubbish Garbodor Mareanie Toxapex These are all the Steel-type Pokmon cards in Celestial Guardians
Besides being called Your Egg, which is just the best name for any card ever (I cast fireball on Your Egg, it is now boiled) its tap ability prevents people from targeting lands, lets you put Treefolk cards on the bottom of your library, and allows you to dump your entire hand of creature cards for no cost
