Thanks a lot for the thoughts inscho. I think you are right on all counts. Int he end my cube is very much a typical cube with some care put into archetypes. And I can see the historical angle is pretty much a novelty, though I don't play Magic enough for it to matter. Like you say, the easiest path is to simply cut the losers. It's worse than lowering the power level, but I'm pretty happy with how decks turn out and the matches are fun. I'm mostly going to play at a boardgame club or with my friends and most people aren't as invested or as good as you or I might be.
For me the biggest issue is that the draft railroads you into the same archetypes, even if there are equally good archetypes available. Part of this is just the result of me drafting my own cube on my own but it's dissapointing how easy is to move into Mardu Aggro compared to Tempo or traditional control.
So yeah, I think I'll just tweak green and remove some of the most questionable archetype support. I can also take out some standouts and tone down removal a notch, but I don't want to make very large changes at this point. I've been working on this cube for months and months and I just want it done. I think it's easier for me to just finish this cube and start another if I want to make large changes.
Regarding Simic and Selesnya, I think the issue is green. White is very powerful in my cube and it has a lot of room for support. Simic is a naturally good colour pair yet I never get those "ramp into Fact or Fiction" decks. Seems I would need to work on that.
To be clear, I wasn't dismissing the value of nostalgia, or maintaining a high power level....or trying to criticize your list. I just noticed a slight discontinuity. So I'm sorry if I came across that way.
(I'm a big fan of ahadabans' Retro Combo Cube which is nostalgia ultra)
Just thinking about an easy way to upgrade green....Have you considered:
over Overrun? or maybe
Recurs with Emry, great with pod/blink/tinker/welders, etc. You lose an iconic card, but either would be a strong pull to draft green over mardu
