How do I make AI for a card game?

so, I'm making a card game and now I'm at the part where I write the enemy AI. For now, the only way to write the AI that I can see is to make several events so that the enemy can pick the action depending on the condition.

But if I do it like this, I'm afraid there won't be a randomness to the enemy AI. I know that this will likely lead to making enemy patterns, but I also want to add a bit of randomness in it.

I'm curious on how others make this kind of AI in their game? Thanks.

You can use random(a,b) or choose(a,b,c...) to create randomness if it's needed.

You're right, it just depends on the parameter I put in the choose() and random() then
