Atomic Fire 「Nuclear Fusion Reaction」
A reaction with low output that leaves Utsuho's cannon charged for later. Planning ahead is not Utsuho's thing, but everyone likes big explosions.
Damage: 1d10(*None)
Effect: Leaves a charge in Utsuho's cannon that can be burned when using any spellcard to add an extra effect.

Divine Wind 「Hell Raven's Regret」
Utsuho fills herself with energy, and charges straight into the foe using nuclear propulsion. The more foes targeted, the longer Utsuho goes, and the more likely she is to feel the impacts.
Damage: 4d10
Effect: If there are multiple targets to be hit, this attack does 6d10 and the dice may be split in any way. If this effect is activated, Utsuho takes 2d10 damage if this effect is activated..
Atomic Fire 「Nuclear Fusion」: Globally increases damage by 3d10.(*4d10)

「Subterranean Sun」
Utsuho summons a nexus of nuclear fusion so massive, it has its own gravitational pull; all matter nearby is turned into dangerous shrapnel. Not a good weapon for dinner parties.
Damage: 1d10
Effect: If the damage dealt to the opponent by this card is 5 or less, Utsuho deals an extra 1d10 damage to that opponent on her next two turns. If it is greater than 5, she deals an extra 2d20 damage to that opponent on her next turn.
Atomic Fire 「Nuclear Fusion」: Doubles the duration of the extra damage dealing (no matter what effect the spellcard had). The base damage of the card is also increased to 2d10.

「Abyss Nova」
Utsuho gathers the power of nuclear energy, absorbing everything used on her for a while and then expelling it in the form of an enormous explosion.
Damage: Special
Effect: Utsuho may not use spellcards for the next two turns, and the damage dealt by this card is reduced by 1d20 if she uses an attack during her next turn. On the second turn following the use of this card, Utsuho deals 3d20 damage to her opponent, plus 1d20 for each spellcard used on her during the duration of this card's effct. The damage may be split between opponents as Utsuho pleases.
Atomic Fire 「Nuclear Fusion」: Utsuho is not penalized for using attacks on the first turn of Abyss Nova's duration(*Abyss Nova deals 1d20 more daqmage, and Utsuho may use spellcards on the first turn of Abyss Nova's duration at the cost of 1d20 damage.)

Mutation 「Heisenburg's Uncertainty Principle」
Radiation is dangerous. Especially when the Control Rod of a very powerful reactor has been thrown at someone.
Damage: 1d10 + Xd10
Effect: The opponent hit by this attack takes Xd10 additional damage, where X is half the amount of damage on the first d10 rounded up.
Atomic Fire 「Nuclear Fusion」: Xd10 is reduced from the opponent's dice rolls during their next turn; this can be split among multiple dice rolls, as equally as possible. The dice rolls are chosen on Utsuho's next turn. (*The total damage is reduced from dice rolls instead)

Hellfire 「Nuclear Apocalypse」
Fission unto infinity. The end of the world.
Damage: 1d83
Effect: Cannot be used until Utsuho is below 50 END. Using this card deals 11 damage to Utsuho.

(*These effects are the ones used if I decide to make Atomic Fire 「Nuclear Fusion Reaction」 deal no damage)
