Board Game Arena

Hello,
I play a lot of single games of Dead cells on BGA. When you beat the boss you can purge a card. I've purged a few cards from Serenade, but I'm certain they don't all appear in the menu where you purge cards, because there's one I couldn't purge.

Also, how many cards does Serenade have? Because she's supposed to have x number of cards minimum (I think 3) but I only see 1 that I can purge...
Help!

I'll stick to this topic because it said Serenade.

To answer Foxman:
- Serenade must have a minimum of 3 cards, there is no maximum, after upgrades.
- You can't purge any Serenade card if Serenade has only 3 cards
- You should be able to choose from any card to purge if there is at least 4 in her deck. Is there a bug here ?

My Question: Serenade - First Player
When Serenade is First player, she should attack first. Nothing in the rules says otherwise.
The player will then play their 2 cards.
There is no reason to let me choose a card before Serenade while she has the 1st player Crown.

What do you think ?

Ah, my mistake ...
Serenade will play here card first if she's 1st player, though I must choose my 2 own cards before revealing hers.
And that was not explicit in the written rules.
