[21:09] <minusX> I'm working it out right now but if anyone wants to comment on this question I just got "if I have Opalesence out making Hoofprints of the Stag a creature and Hoofprints gets pinged by Olivia then Opalescence gets blown up, is Hoofprints still a Vampire?"
[21:10] <bimmerbot> Is Hoofprints a creature?
[21:11] <minusX> !hoofprints of the stag
[21:11] <Datatog> Hoofprints of the Stag {1W} |Tribal Enchantment -- Elemental| Whenever you draw a card, you may put a hoofprint counter on Hoofprints of the Stag. / 2W, Remove four hoofprint counters from Hoofprints of the Stag: Put a 4/4 white Elemental creature token with flying onto the battlefield. Activate this ability only during your turn. · LRW-R
[21:11] <bimmerbot> Oh, it's tribal.
[21:11] <minusX> Yeah
[21:11] <bimmerbot> Is there anything stopping a tribal card from having a creature subtype?
[21:12] <minusX> No
[21:12] <bimmerbot> so...
[21:12] <minusX> Opal doesn't add or remove one
[21:12] <bimmerbot> what about Olivia?
[21:12] <minusX> !olivia v
[21:12] <Datatog> Olivia Voldaren {2BR} |Legendary Creature -- Vampire| 3/3 Flying / 1R: Olivia Voldaren deals 1 damage to another target creature. That creature becomes a Vampire in addition to its other types. Put a +1/+1 counter on Olivia Voldaren. / 3BB: Gain control of target Vampire for as long as you control Olivia Voldaren. · ISD-M
[21:12] <minusX> She adds it
[21:12] <bimmerbot> right
[21:13] <minusX> I was going to point out the layers to him I was just pulling up everything and pasting here
[21:14] <minusX> Didn't even think about it being layers at first (I guess I shouold always jump there with opal)
[21:14] <bimmerbot> Opalescence is just the enabler for Olivia to target it.
[21:14] <minusX> ya
[21:14] <bimmerbot> It's not really that relevant to the question.
[21:14] <minusX> True
[21:15] <bimmerbot> The question at hand is "will Olivia's type-change effect continue to apply to an object after it stops being a creature"
[21:15] <minusX> As far as I can tell there's no time restriction for it so it would stay
[21:15] <bimmerbot> right. It will try to apply in Layer 4.
[21:16] <bimmerbot> If the card wasn't tribal, that continuous effect would be meaningless.
[21:18] <minusX> "If a permanent ceases to be one of its types, the subtypes correlated with that type will remain if they are also the subtypes of a type the permanent currently has; otherwise, they are also removed for the entire time the permanent's type is removed."
[21:18] <bimmerbot> Yup
[21:19] <minusX> also "When one or more of a permanent's subtypes changes, the new subtype(s) replace any existing subtypes from the appropriate set (creature types, land types, artifact types, enchantment types, spell types, or planeswalker types). It won't affect the subtypes from any other set, and it won't affect the permanent's types."
[21:19] <bimmerbot> Except when it's "in addition"
[21:19] <bimmerbot> like Olivia is.
[21:19] <minusX> Right forgot it said it there
[21:19] <minusX> reading
[21:19] <bimmerbot> that's not "changing" so much as "adding"
[21:20] <minusX> So since vampire can be a subtype of tribal *, it stays?
[21:20] <bimmerbot> Yup!
[21:21] <bimmerbot> Who would ask you that question??
[21:21] <minusX> A friend of mine haha
[21:21] <minusX> He and his brother get some weird interactions
