It serves as proof of the unbroken, royal line of succession.
Explanation
A standard spell that lets you summon a specific kind of Ice-type unit after you've retired any number of units.
It also has a trigger ability that lets you return it to your hand after it's been exiled from your discard pile, but only if your partner is an Ice-type unit.
Using these effects will let you consistently summon large units after retiring.
This makes it useful for decks that try to summon cards like 'Snow Rune, the Ice Queen'.
Furthermore, if you have a consistent way to exile this one after playing it, the second ability makes it so that you can keep bringing it back to your hand to cast again.
If you have something like 'Extreme Cold', you can also repeatedly use it as the cost for abilities that need hand cards.
Keep in mind however that it does require your partner to be Ice-type.
