"Lost in Crowds/Into Thin Air" restriction should be moved to the superior text.

At inferior the "Lost in Crowds/Into Thin Air" interaction is functionally identical to numerous other free inferior obfuscate +1 stealth and Inferior Into Thin Air combinations.

Either one being used at superior is problematic, both used at superior clearly screams a need for the current card text to exist; mitigation I feel is simply unjustified if both were to be played together at inferior.

If anyone could be so kind as to illuminate pertinent considerations I have overlooked I will be most appreciative.

Seems like good QoL for v5 in my humble opinion.

I think the real balance question is "Why is Into Thin Air free?"

Into Thin Air is not totally free as you don't replace it till next unlock phase, reducing your hand size is something important.

Regarding about only superior, no idea why it is there, but it is easy to track like that and trying to specify that you cannot play at superior Into Thin Air and Lost In crowds in the card would probably make too much text and get the card more confusing, right now it is very clear, you cannot play both, period. Easy to understand and easy to apply. That's just my 2 cents
