See Challenge # 112. I have this image of Sahala towns having people on the gates who are like the opposite of gatekeepers, welcoming in almost any comers with a smile and directions to what they might most need. Like the greeters on the door of a good welcoming church.

The "add " mode is a little odd, but I think it derived from the sequence of thoughts "Sahala have special crystals to preserve knowledge" -> "Sahala must have mages or smiths whose job it is to create these crystals" -> "Those crystalsmiths probably make other, more everyday kinds of crystals as well" -> "Sahala society features a few different kinds of everyday magical crystals" -> "Being so welcoming, the gatekeeper welcomers would give a minor magical crystal to anyone who comes through the door".

I love the concepts here, I didn't have a good idea of the Sahala. It does feel a little odd to have the choice, maybe they should be on separate cards, or be rare and get both benefits?

Mmm, yeah, you're right, separate cards would make more sense. They could probably both be common then, by comparison with Ivy Lane Denizen. Or the "and" mode could probably still be uncommon: I was thinking of this as similar to Juniper Order Ranger (gaining mana instead of getting bigger itself).

That makes sense. I'm still weak at development, I would have guessed "everything gets +1/+1 counters" was rare, not common :)

I think the abilities should be split up among two different creatures. After all, the mana ability can be quite strong. It's no Mana Echoes, of course, but still.

This is a very good representation of Sahala's welcoming nature.
