To you that have cubes bigger than the amount of cards that actually get drafted ... have you ever seeded some cards into the draft pool? I don't mean in specific packs, but lets say you know that your players will only see 288 cards (a six person draft with four packs of 12), and there are those six cards you really want to get some impressions of. Would you say it's legit to just shuttle those six together with 282 random cards and make packs?
For some silly reason it feels wrong to me, almost criminal
as the curator of a
1337-sized list and
soon-to-be 690 list: no, i've never seeded packs. i prefer to see the cards in their natural context, as that's the true goal and most honest view (to testing purposes) imo
i'd likely make an exception if there were a very specific thing i needed to test, purely to speed up that process. but would revert to the standard unseeded packs quite quickly
the only things i 'seed' are core cards i distribute for free, eg give everyone a prismatic vista, or a cogwork librarian, or something along those lines
that said, i don't think it's 'wrong' to seed, just that it's something that hasn't really appealed to me
[edit] i could see a project where seeding is itself a texture of the cube. eg, have packages tagged, and seed one or more packages at the beginning of each draft according to what flavor the drafters are into that session. eg, spellslinging, graveplay, typal, sets/eras, etc
