rare lost origin cards Pokemon Complete Reverse Holo Set Pokemon - Iscan 207/196 Lost

What is the rarity of this Serena card

It is quite powerful but comes with risk

The card is particularly useful in Yu-Gi-Oh Duel Links where it's part of a combo to combine it with Secret Pass to the Treasures to allow it to attack directly, and Union Attack to boost its ATK power tremendously while you control 2 other decently high-ATK Monsters (which won't nullify the restriction on Secret Pass to the Treasures being able to only use its effect on Monsters with 1000 or less ATK)

One of the other popular commanders from the product, Im guessing, Syrix is finally a Phoenix tribal commander

USA buyers importing Japanese cards might notice loose holders
