my first time making a monster that gives an Xyz monster an effect

[Face McShooty]

Now I'm unfamiliar with Xyz monsters and everything, but after doing some research, I decided to come up with a monster that gives a Xyz monster an additional effect, at the cost of detaching it.


If this monster is used to Xyz Summon an EARTH Machine-Type monster, the Summoned monster gains this effect:
You can detach this monster during your Main Phase and your opponent cannot activate any Spell or Trap cards during the Battle Phase.
