In a four player game with BCFs, each player puts the following cards down:

1. Ordinary Day
2. Ordinary Day
3. War Zone
4. Earthquake

Player 1 uses his Ordinary Day to cancel the effects of Player 4’s Earthquake. Now, here is my question, can Player 2 use his Ordinary Day to cancel the effects of Player 1’s Ordinary Day, making Earthquake an active BCF, since Ordinary Day is worded as “Cancel a single target battlefield condition.”

Yes

Thanks, I just wanted to make sure that I was correct before I do that in a game.
