UR Ultra Rare Apple Magician Girl X FIRE Level 3 [ SpellcasterEffect ] ATK 1200 DEF 800 Once per turn, if this card is targeted for an attack: You can Special Summon 1 Level 5 or lower Spellcaster-Type monster from your hand, then change the attack target to it, and if you do, the attacking monster's ATK becomes half its current ATK
There are lots of Eevees featured in the Team Gallery subset but like Evolving Skies, Umbreon is usually the most requested card that comes out on top
You blink Akroma in response
