Description
reported on discord, occurred when [[Hulking Metamorph]] was copied with [[Mendicant Core, Guidelight]]
This appears to be the only cast without an instanceof check, so it must be researched, how a copied stack object can end up with case PROTOTYPE but not be a PrototypeAbility - something calling `getCharacteristics()`

Research direction
Start at Mage/src/main/java/mage/constants/SpellAbilityCastMode.java around line 76 and trace getCharacteristics() for a copied Hulking Metamorph stack object created with Mendicant Core, Guidelight, especially the PROTOTYPE path. Done means explaining why the object is not a PrototypeAbility and resolving the ClassCastException for that scenario.
