This card cannot attack the turn it is Summoned. If "Toon World" on the field is destroyed, destroy this card. While you control "Toon World" and your opponent controls no Toon Monsters, this card can attack your opponent directly. You can Tribute 1 monster; inflict 500 damage to your opponent.
Not really, Gemni Elf is actively ran in every variant in the TCG- DMG is is only ran as an optional choice in a beatdown variant. It’s only slightly better in Duel Links for that reason, but Elf is still the better and more usable card overall
Keep in mind the only reason Toon Gemini Elf is so common is because of how bad the other low-level Toons are. It's not actually important to their strategy at all, unlike a card like Toon Dark Magician or Red-Eyes Toon Dragon. I wouldn't consider it a staple, just a card you kinda have to include because you have no better options. DMG and Red-Eyes are clearly the main monsters in DL.
F2P never dies
Really great card, I like when they give us good cards for free.
