My response was just tongue in cheek 
I don’t try to build positions on cards, so there’s not some larger reason at play for me.
As far as I know, promos have been doing very well in this boom, so it’s possible they will do so again in the future (or continue to do well). I think most people that lean more towards collecting vintage (which E4 definitely does) will poopoo on the current state of the market right now. But it’s clear that that isn’t the prevailing mindset, or the market wouldn’t be where it is at this moment. I haven’t followed the thread at all, but the title here sounded relevant enough to your discussion point.
