This card is treated as a Normal Monster while face-up on the field or in the Graveyard. While this card is a Normal Monster on the field, you can Normal Summon it to have it become an Effect Monster with these effects.● This card becomes EARTH Dinosaur-Type. When this card destroys an opponent's monster by battle and sends it to the Graveyard: You can Special Summon that monster to your side of the field in Defense Position, and if you do, it becomes Zombie-Type.
Special summons destroyed monster to your side of the field.
Needs another normal summon to have its effect be available as well as gaining the benefits of jurassic world.
Lack of zombie supports.
If used in Rex decks with the field spell Jurassic World, you can use Super Double Summon during enemy's turn to activate its effect and become a dinosaur. If it destroys their monster, you can special summon it on your side of the field.
Ok, using the effect of Skelesaurus against Blue Dragon Summoner is a huge disadvantage, Blue Dragon Summoner's effect activates for your opponent not just once but will also activate a second time for them when it is destroyed from your side of the field. An absolute nightmare when dealing with Exodius.
