New Year ninjas always lack strength and heat. Although it is copied from the mobile game, I have to say that the image of Deidara is indeed suitable for the Year of the Dragon.
Mystery C2: New Year's Masterpiece Selection: Attack the enemy faction for up to 7 bodies to deal fire and earth damage, and the selected target suppresses bad status immunity (lasts until the end of the turn) and inflicts immobilization. If the selected enemy has been marked with 2 bombs, this skill will be hit, and the 2 bombs hit on the target will be increased to 3. The core of the monomer control is to hang the explosive point state. This state damage is calculated independently by the city, and it drops 21% at a time, which is quite exaggerated.
Basic attack clay cannon fire! : Attack a random rampant enemy to deal fire and earth attribute damage and mark the explosion point, with a certain chance to inflict non-immune and dispellable ignite (which lasts until the end of the turn), and randomly 1 body to cause knockback. If the target has been marked with a blast point, replaces the ability effect. 
Chase Clay Cannon: Burst Wyvern: Chase down enemies with small or large floats, inflicting knockback and marking the explosion point, this skill will be hit, if the target has been marked as a blast point, the skill effect will be replaced. 
Trigger the Slime Clone: At the beginning of the battle, summon 1 clay clone on the field based on 80% of its maximum HP, and when the clone is defeated, it will trigger the lore - Earth Escape: Earth Dragon Hidden Technique. 
Passive Artist: Deidara is immune, you can gain up to 2 skill points, and when the upper limit is reached, you can trigger an additional 1 clay clone, and for every 1 clay clone in your team, Deidara will deal an additional 8% increase in damage and ninjutsu. In addition, Deidara will trigger 1 clay reload before each action. 
As a bond ninja, he has all the basics he should have. Ao Yi relies on chasing and fighting perpetual motion, and if there are conditions, it must be hit, and the clone is stable when it resists damage and kills, and it also has a level of immunity. Hanging on to the anomaly also has good damage.
But his shortcomings are also very obvious, he doesn't have lifestealing to last, his cultivation speed is slow, his clone will be shocked, and his perpetual motion is also unstable.
Overall, compared to the previous two years of New Year Ninja, there is progress, but it is not strong enough.
