To use a card in Speed Duel, it needs to have the "Speed Duel" symbol in the card

Maybe if you got rid of the position-changing, let it Summon something with the same Level as the monster (or, if you're afraid of Endless Decay shenanigans, make it any Level 4 or lower Zombie), and when this is destroyed, you could add a Zombie with the same name as what you Summoned from your Deck to your hand (you probably could attach this card to the monster like how Call of the Haunted does with its "If that monster is destroyed, destroy this card" thing).
