it is tempo and surprise damage
Since youre in Bant colors, there are plenty of ways to manipulate the top card of your library and make sure you have extra land drops to skip through the cards you dont want
Open dueling or no, feel free to pick up a deck and get to battling
Example: A player casts Cytoshape, causing a Kruin Outlaw (the front face of a double-faced card) to become a copy of Elite Vanguard (a 2/1 Human Soldier creature) until the end of turn
So despite Ragavan, Nimble Pilferer being a busted Magic card in the format and maybe the best red card existing, its still manageable for the majority of decks
But giving a definitive place for cards like Ninja of the Deep Hours, Tetsuko Umezawa, Fugitive, and Dimir Infiltrator to thrive was a master stroke, in my opinion, legitimizing a fifteen year old tribe
