The point of my recap here is that there are rare serialized versions of Sol Ring that represent the other rings as well
For cards in a perfect condition, or those recently pulled from a booster, the exceptional Gold Label & Black Label (CCC 10), indicative of a card in pristine condition, are accompanied by a very sharp increase in value compared to an ungraded version
With max speed, all your creatures have first strike, which is wonderful by itself, but it becomes stellar with the pump from this creature
With the prevalence of blockers in Avatar: The Last Airbender , a card like Enter the Avatar State that allows an attacker to get in unblocked becomes more important
Because Finality counters only care if the card they're on goes to the graveyard, you could use a Flicker effect (of which there are many in Esper) to exile your artifact before it's destroyed and return it without a counter
