| Ability | When Topdecker enters the planet, it deals 1 damage to any entity. When Topdecker is put into a junkyard, place it as the fifth card from the top of your deck. |
| Rules clarifications | – Topdecker’s effect triggers when it’s put into a junkyard from anywhere, not just from the planet. – If your opponent has somehow stolen your own Topdecker and it dies, it goes to your junkyard, not your opponent’s, so it’s placed as the fifth card from the top of your deck, not your opponent’s. |
