I know it's not invincible, but it should hopefully die less than the average commander once it's functionally hexproof. As far as the other non-token permanents that generate tokens, a lot of those won't die in a sweeper so recurring a big chunk of permanents becomes less likely. Based on the curve of my deck I rate the ramp capabilities of the card pretty low, so I don't think the uses add up to making it worthwhile.
As far as fetches vs targets, I want to have a play with the deck to see how it does. After a certain point, hopefully I should be able to force a trade with a token every turn (or maybe trigger myriad, high market, etc), but for the early turns fetches are my only realistic way of triggering her so I don't want to be too light. I think ten targets should be okay, though, my curve stops at 5 and even stuff like the devotion flashback is still easily achievable even with only fetch targets - and I've also got other 11 lands which can tap for mana normally, plus 6 mana rocks, so getting to 9 doesn't seem likely to be a problem. I think I'd be more likely to include more utility lands than more fetch targets, I don't think they'll be necessary.
If I do cut fetches, probably the non-esper capenna ones first? panos seem better since they can most easily be held onto to trigger later, rather than needing to fire immediately.
@duducrash Tocasia's is fine and was considered, although it's mostly just a conditional
Phyrexian Arena - I might include both depending how I feel about the draw, although honestly I might be better of running equipment tutors for skullclamp since it's massively stronger than any other draw engine for this sort of thing.
Welcoming vampire, and anything that cares about low power, is antisynergistic with my commander so those are out.
Bennie was considered but I don't love a creature-based draw engine for a go-wide deck since it exposes us more to wraths. And also he's kind of a phyrexian arena.
Idol should maybe be in there, since it's cheaper and not a creature.
Field of the dead should 100% be in there. Not sure if I just wasn't paying attention when leafing through lands, or if it's in another deck somewhere, but I'll track it down.
