I actually just did. Some Red-Eyes players are running a copy of Gandora in their deck to summon off of this to nuke the opposing field. And because it doesn’t count as a normal or special summon- Gandora doesn’t 🔥 itself during the end phase.
I know that's a thing. But it was never common, and I've never actually come across one in practice. Just a couple of the other "common" use of it (Steelswarm Hercules.)
I'd call it "Skill Summon" but we don't have an official term for that kind of summoning. I guess that's why most skills use the wording "place" instead of "summon".
