If you mean the /4 bit, I think any time you would earn a regular card (5 waves) it gives you a bonus. I presume if you finish frenzy you wouldget the all 4 of the bonus ones (as frenzy gives 1 per per 5 waves, so wave 5 and 10 and then if you finish wave 12 gives an extra 2), I imagine TC’s bonus card system doubles it but I am not 100% on that.
In escape its 1 extra card per act you complete and must be the daily (or weekly) hive. If its a 2 act hive and you miss the first act you would only get a bonus card ofr the second act.
I haven’t done a heap of testing with this so anyone feel free to chime in if the results aren’t matching what I am saying
