Boltund will be getting its 2nd V card in S8 Fusion Arts, which is released in Japan on September 24th. It will then become a part of our Fusion Strike set on November 12th. Thanks goes to JustInBasil for translations!
[L] Smash Turn: 30 damage. You may switch this Pokemon with 1 of your Benched Pokemon.
[L][L][C] Electrobullet: 120 damage. This attack does 30 damage to 1 of your opponent’s Benched Pokemon. (Don’t apply Weakness and Resistance for Benched Pokemon.)
When your Pokemon V is Knocked Out, your opponent takes 2 Prize cards.
Weakness: Fighting (x2)
The placement of Boltund V in the set, 34/100, essentially confirms Boltund VMAX being featured in Fusion Arts as well. This is because Toxel is 36/100, and there are not any Electric-type Pokemon between the two, thus leaving room for only Boltund VMAX.
