I always get confused about how Splinterlands card levelling works for combining more than maxed. I feel like they have changed that many times and I just haven't bothered to keep track at how it works.
I remember seeing a lot of Alpha common cards that had over 400 BCX combined, when max only takes 379 BCX

I thought they stopped the over-combining from being possible. But I do remember back in the Alpha/Beta days seeing some that were over-combined. It was a hot topic for a minute.
