RK has the same passive effect as Frisk, making its owner immune to any DMG. However, unlike Frisk, it doesn't have the HP they have, but also not the cost.

Instead, when played, RK will add a Puzzle Box to the enemy's hand, making it similar to Annoying Dog when wanting to overflow their hand. This Puzzle Box is a simple 3G spell that, when used, will silence all enemy RK's, making you no longer invulnerable.

Because of this, it's not a good idea to place multiple RK's on the board at once, unless the enemy's hand is already full and as such, cannot obtain a Puzzle Box.

Avoid using Receptionist 3 if you find out that the oponent has this card by using Spy or Eye, since the puzzle box will not be added to your hand. This goes double if your enemy has taunt monsters on the board.
