Cannot create comparer [Answered]

I'm trying to make a comparer to pass around but it's refusing to let me define it. Here's the code 
Comparer<Card> trumpComparison = new Func<Card, Card, int>((card1, card2) => (card1.suite == trump ? 1 : 0) - (card2.suite == trump ? 1 : 0));
Comparer<Card> trumpComparison = new Func<Card, Card, int>((card1, card2) => (card1.suite == trump ? 1 : 0) - (card2.suite == trump ? 1 : 0));
Card in this case being 
public readonly record struct Card(Suite suite, Rank rank);
public readonly record struct Card(Suite suite, Rank rank);
I've tried doing it as a lambda and it complained it wasn't a delegate. So instead I give it a func, and now it's telling me it cannot convert it to a comparer. What am I missing here?

you need to do Comparer.Create(func)
