This card seems pretty bad if the set is supposed to be drafted. I don't even see any monocolor themes here.

This is me running out of ideas for low rarity flyers, since the set needs a lot of them to make the tunneling mechanic live. I'm gonna cut it if I find a better idea.

Hmmm, it's usually easier to come up with cards concepts if you give the card slot a specific purpose.

Just going with something not so color intensive would be alright. Like a functional reprint of Makindi Griffin or Skyswirl Harrier.

A somewhat interesting idea I came upon while checking for similar cards was the idea of printing Wall of Swords at common. In some environments it could be rather oppressive, but seeing how numerous and spread around colors tunneling is, it could work.

At some point though, it might be better to stray away from having this many reprints (though I just suggested another one). Maybe not as this stage, but perhaps later on you could simply try come up with your own variants of the said cards. For now, using reprints as "placeholders" can work well. Sets certainly have couple of reprints usually (core sets much more so) but IMO when that numbers starts to creep around 10+ it's somewhat... troublesome (also boring)?

Personally I would reprint cards when the reprinted card would have in this new environment a "twist" on it, like Terror in original Mirrodin (being suddenly much weaker) - or makes sense flavorwise, like Renewed Faith in Amonkhet. This is why I suggested Wall of Swords since here it could play somewhat unexpectedly. Something like Alabaster Dragon is not really interesting, well it's an old card that's a white dragon so it's cool that way, but IMO it should "reserved" for a set where either being a white dragon matters or being shuffled or causing shuffling matters.

I don't think a high reprint count is troublesome. It could be boring, but I think it's fine in a place where the flavour makes sense and the mechanics are what you want.
