MAYBE 2 copies if deck was meta which it isn’t. People forget you have to spend a knight on the field which isn’t a zero cost like Champion Vigilance or something that is just graveyard presence like other meta decks. It’s not even a hand counter trap like Blackwings has.
Also even with this card at 3 Knights are not meta so it might not even get touched period. Delta is meh boss too.
Omni negate trap in trap card era? Honestly I'm surprised they made this an SR.
