Problem: I'm planning to go all-in on the current limited banner to get as many copies of 'SilverAsh (Frost)' as possible. Based on the Orundum and Originate Prime shown in my screenshot, and assuming the worst-case scenario where I never pull him directly from the gacha, how many copies can I ultimately obtain through the spark/exchange system? Note that I have already used two exchange tokens to get one Wiša'del and one Skadi the Corrupting Heart.
Answer: 6+1=7
