You can target 1 other "Graydle" card you control and 1 card your opponent controls; destroy them. During your End Phase: You can add 1 "Graydle" card from your Deck to your hand. You can only use 1 "Graydle Impact" effect per turn, and only once that turn.
The Graydle monsters that want to be destroyed by card effects, especially Graydle Alligator, have not yet been released making the removal effect less practical. Because of this you might want to destroy a Graydle Split or another Graydle Impact you control. The search effect is good for getting Graydle Combat for protection, or Graydle Slime Jr. for synchro plays.
