Intrepid Paleontologist

2023-11-10 Finality counters work on any permanent, not only creatures. If a permanent with a finality counter on it would be put into a graveyard from the battlefield, exile it instead.

2023-11-10 Intrepid Paleontologist must be under your control in order to start casting a Dinosaur creature spell using its last ability, but it doesn't need to stay under your control throughout that process or be under your control as the spell resolves. If, for example, you sacrifice Intrepid Paleontologist to pay an additional cost of the spell or it's destroyed in response, the spell will still resolve normally.

2023-11-10 Multiple finality counters on a single permanent are redundant.

2023-11-10 You must still pay all costs and follow any timing restrictions and permissions for Dinosaur creature spells you cast from exile this way. Normally, you'll be able to cast them only during your main phase while the stack is empty.
