The debuffing queen of PVE, Leviathan is a card that started mediocre and has quickly jumped to a powerful card. With the rapid changes and deployment of buffs and bosses that focus around the use of them, Leviathan's ability to completely remove positive buffs is a useful, if not reliable way to change the tide of a battle. Couple this with a 30 cost stat total (The highest in the game even), and Leviathan is a solid and useful card to have around.
Leviathan's power in PVE lies heavily in her ability to remove buffs from the enemy, coupled with new dungeons that have bosses revolving around their buffs (Such as Chen's slowly increasing attack power with his agility gain, and Senju's ability to flash +5 either attack or defense). A proc will neuter some of these and greatly hinder others- however, the rate seems to have iffy chances. However, her attack also is a typical 3-hit, meaning she can still output solid damage on red targets and claw-weak targets. In PVP, she is the only solid blue claw attacker in the game at the moment, only sharing the field with Nadja, Stringray X, and Lao Hu, two of which are questionable and one that does not work in PVP very effectively.
The downsides however, are there- Her subskill is somewhat iffy, as while a +1/+1 is incredibly useful, it is only a chance and the cards that will benefit from his skill icon are small. Her actual attacking total is the weakest of all the Archdemons, and is in the lower range for 1400+ attackers- and in PVP, while her damage is still very solid, her sub-effect will have little use. She is also arguably contested in PVE by Beelzebub, who does what she does with the addition of stealing the buff.
Overall, Leviathan is perhaps the weakest of the Archdemon still, but still a very powerful and useful card to have around.
