Now that you mention it, Ingester may be too weak these days. I've been meaning to throw in the blue saga from DOM, but unsure if it can just be a replacement for ingester?
Don't forget that Ingester is blue removal, which is pretty rare. A control deck can play Ingester and be happy with the 2-for-1. The saga is a tempo card, so it fills a different role. Depends on what you want to do with your cube.
Interesting. A naive analysis of my cube finds 207 creatures, 13 creatures with toughness>2+flying and 4 with reach. In addition there may be some that are slipping through the cracks like an outlastedAbzan Falconer or an evolved Cloudfin Raptor.
But for stonewalling, you are probably looking at less than 10% of creatures. And then there are another 16 (~8%) flyers that will trade with it. Hmm. I wish you got the tokens when it died no matter what.
One of those is enough to stonewall the Bomber, in that case you played a Winddrake. Add to that all the flyers that just trade and all the board states that will let your opponent just say "sure, I'll take two, trade in your 2/2 flyer for a 1/1 token please".
It was in my pauper cube when I started cubing. It was alright. Peasant has a lot of flyers who just stonewall a 2/2, so in addition to the statline, that could be a problem, as Bomber does need to connect. I don't think it'd be worth a guild slot.
I didn't expect it to do that well either, and I'm not 100% sure how to explain why it worked. Maybe it was related to people running slightly different decks at the very beginning of the format (I haven't drafted for a week), but it did some major work for me, including against decks that ran "superfluous" creatures. So I don't think that's it. One draft I had a Dimir deck with two Plaguecrafters, all I played against where other Dimir decks... and it was still good. It was an aggressive-ish midrange Dimir, so the board never really built up to where they had lots of extra stuff to sac. There was only one situation like that and the sac trigger still worked out ok for me, because he had to sac a 1/3 and I got rid of a 1/1. That deck also had two of the "shuffle four cards from your graveyard into your library" counterspells, so it was easy enough to recur Plaguecrafter, something that we can do in cube as well, although by other means. And there's always the discard option as well, combined with bounce spells or just to hit their last card. The discard part does add a lot of versatility.
I haven't, but Plaguecrafter has been doing really well for me in draft, so I'm probably going to try it in cube. The fact that it makes opponents without creatures discard has been suprisingly relevant in my games.
Tacking a Lightning Strike onto a Lightning Bolt is fine, but hardly amazing. For a lot of the other one and two mana spells (which is what we'd copy most of the time) it's just not worth it imo.

That said, I do use packs of 12.
