Though, it is the only magic monster with double strike, which makes it a bit more unique at least.
There is also a legendary Dragon gladiator with double strike magic attack, Larisa Kerato I believe.
My reward luck might be a touch bit better, but sadly they have mostly been concentrated in the underwhelming soulbound Dragon legendary Berix Snakeye -- I have NINE! GFL BCX of this card. I wish I had more of Kulu in Water and Skok in Death. Oh well, sooner than later I presume. I have a pair of rares maxed out, and finally my first RF max common with 400+ BCX. Over the next month or so I'm hoping to have about 50% of the new set maxed in either RF or GF versions (though as a GF player I'm more more keen to have maxed out GF soulbound cards). Good luck to you with your fully maxed Sorrel and I wish you better luck with your rewards RNG.
