After entering the field, it needs to preheat for 2 rounds, and it can only launch an attack in the 3rd round.
If the card is replaced midway, the 3 rounds have to be recalculated when it enters the field again.
It will be restricted in the mid-to-late game, and there is a potential risk of revealing the other party's King Card in advance.
In the early stage when the opponent's actions are sufficient, it can provide some utility.
However, generally speaking, Ree Shil will choose to use Chaos Soldiers Hill in the early game.
The scenery cards Ree Shil has so far are just these six.
The first problem he encountered was that these six cards did not fuse with each other.
Then it was the problem of the number of cards.
Like regular cards, only 3 substitute cards can be carried for 1 main card in the scene cards.
That means Ree Shil can at most carry 4 scene cards for rotation.
So the first wave of card-making targets is to solve the problem of Scenery Cards.
