Shelob, Child of Ungoliant has the ability
Whenever another creature dealt damage this turn by a Spider you controlled dies, create a token that's a copy of that creature, except it's a Food artifact with "2, Tap, Sacrifice this artifact: You gain 3 life," and it loses all other card types.
According to the rules text, "loses all other card types" includes subtypes. However, since "Legendary" is a supertype, does that mean that the Food token does become Legendary if it comes from a Legendary creature dying?
