Having a Clone in the command zone, even one that only hits your own creatures, is hugely valuable
Deep-Slumber Titan Four mana for a 7/7 would be a great deal, but the drawback on this card is just a little too big
Additionally, because Beach Court is a Stadium card, it also serves a way to remove your opponents Stadium card from play, including especially hostile Stadium cards like Path to the Peak
If you do, the other player still gets the card with cascade on it, but those cards are usually a lot less powerful than whatever the other cards in that players deck are
I have the feeling the card might be too powerful: It thins the deck by searching a copy of itself, it comes with a decent ATK of 1800 for a Level 4, and the last effect can set "Chain Dog" up, trigger "Heraldic Beast Leo", and I don't know what else
This was a brutal set of games, where the deck functioned well but our opponent's decks were also firing on all cylinders and were up to the task
