Cards which can change colors

[FranAvalon]

Cards which can change both the color of spells and the color of permanents: they have two abilities, but they should have one
Cards which can change both the color of spells and the color of permanents: they have two abilities, instead they should have one.

These cards are: Chaoslace, Moonlace and the other laces, Blind Seer, Eight-and-a-Half-Tails, etc. Search for "spell or permanent becomes".

Currently if you make one ability out of the two the game crashes as soon as you're able to cast/activate that spell/ability. That's because of GetTargeting()->SetSubjectZoneId(ZoneId::Stack | ZoneId::Battlefield);. It doesn't like it, when there are two zones.
