Comparable to Ifrina, Mercurius is yet another Power-Up enhance card with a few differences.
She's got a higher cost, better stats, a better Super Fusion, and a Sub Skill that can be used on a wide variety of cards.
Needless to say, Mercurius is quite useful for helping dish out major damage and is a solid addition to any deck.

Mercurius gets an improvement in her Main Skill in that now the strength of her Power-Up increases with better hands made. Just making a Straight+ gives you a 2.10x boost, and can reach all the way up to 2.30x with a Four Card+ hand. That said, Awakening has done nothing but improve Mercurius' abilities.
Pretty much what it says: A straight 15% Skill Boost to any Water-type card. Quite good for Support cards.
Similar like before, but the Skill Boost increases to 20% now. However, an interesting quirk is that if the other two Subs on your Main Card are Blue, then Mercurius gives a 25% Skill Boost instead. This can be particularly useful if you have multiple Mercurius you use as Subs or use her with other Blue Subs.
Mercurius got a pretty handy Awakening Skill. When played in a hand and you take damage during the turn, she grants 5% Damage Reduction as well as a 20% chance to grant +1 DEF to yourself. The Damage Reduction is no doubt handy, and the DEF Buff is useful too, though it has a low chance of activating.
Unsurprisingly, Mercurius bears a close resemblance to Hatsune Miku, the famous Vocaloid.
