You can only use this effect of "Coral Dragon" once per turn

Each Player can only control up to 5 Monsters and 5 Spells/Traps (including Pendulum Monsters activated as Spell Cards but excluding Field Spell Cards) at any time

It is a field monster removal effect made with an equipped card, and the timing of activation is somewhat limited

Neither player can activate cards or effects in response to this card's activation

This can unintentionally let you identify specific cards in your deck, something that's not allowed in competitive play
