Overall, Gift of The Mystical Elf could see situational play in specific decks but may not be a staple in most competitive strategies

It seems to be in a bad place because it depends on the expectations of the other party, but I think it can work interestingly if you devise it

When this card is sent to the Graveyard because the equipped monster was used as an Xyz Material: All Xyz Monsters you currently control gain 300 ATK

give your opponent control of this Defense Position card by moving it to their zone adjacent to the target, then if your opponent controls exactly 2 "Centerfrog" in the Main Monster Zone, gain control of all monsters in between those 2 cards

The card already had the downside of not being able to attack with its 3000 ATK

It can either extend into Cyber Dragon Infinity or Cyber Dragon Sieger by Summoning 2 Cyber Dragon from the Deck
