The idea is simple:
Make symbols left from the name in the normal room to show what us player expects, when we choose an opponent. =)
We want the possibility to decide, wether we play vs "big deck" or not, but we cant see them before the game.
So there are many run-aways at turn 1 or 2, since we pick the wrong opponent.
Bouth player are angry: one because he want an opponent on eyesight (not beeing slaughtered), the other because a win in turn 1 or 2 does not count as win.
But we are too less player, so a seperate room is a bad idea.

The solution:
Show the strength of the decks in the room with a small Symbol, like the head of:

= Normal deck without legends / event cards

= minimum 1 Legendary inside

= minimum 1 Eventcard (and/or legendaies) inside
Now an "Amnezy deck" could also fight vs a "Lucyan deck", if bouth player want that. But they know before the fight, what they have to expect.
Also if I want to invent some smaller Levels to play with me I can choose to play a lucyan-deck, too.

Another idea was to just mark the 3-in-1 chars, because in adventure mode all the bosses are marked, too.So player can avoid runaways by surpisingly have the wrong, too big, opponent. =)
