[The first thought Shun jumps to there is probably a bit of an obvious one.] So they're like an advancement of Pendulum Monsters - a Field Spell and a monster instead of a Continuous Spell and a monster. [He can't help but wonder how that manifests in a duel, though...how could something be both a monster and the playing field?

He gets distracted by the last comment though, and resists the temptation to roll his eyes even if it's hard to tell with the colour the bird's eyes are.]

I'm not saying it isn't, but Real Solid Vision was already abused to hurt and maim innocent civilians. I don't see how having actual monsters walking around with you would make that any less likely.
