Knights' Gambit $4
Action-Duration
+1 Action
At the start of your next turn:
+2 Cards
While Knights' Gambit is in play all cards that affect the player to the left now affect the player two players to the left instead.
I don't quite understand this card. I can read this in two ways:
1. Everyone is affected. For example, when you play Masquerade in a 3-player game, it actually causes you to pass to the right. Similarly, Tribute affects the person to your right.
2. It only affects the person to your left. This makes a lot of things super weird (in Masquerade, they get nothing but have to pass two?), so I'm going to assume you don't mean this.
But case 1 is not all that great. It doesn't have interaction with many cards, and even when it affects something it doesn't really confer much of an advantage. And hey -- in 2 player games, it causes Masquerade to read "pass 1 to yourself"? And the same thing if two have been played in a 3p game?
Then again, this is just a card inspired by another game. I don't play a lot of chess though, so I don't quite understand the relation here.
