While we've already covered the stats, I do believe they should be re-told here, not only to keep in the theme of Soul Calibur (A tale of souls and swords eternally retold, right?), but because they just seem plain bad. 5 difficulty, 2 control, and no block at all. Plus, it's Unique. 2 CC wins games, or will enable you to win games, right? So it better be good. It better be great. It better be... awesome. Here's the effect : " E Commit : Your attack gets Multiple : 1. "

Uh... okay. Right. Sure, whatever, but is there anything else?

Nope. That's it. That's the entire card - it fits in a nutshell. It gives any one of your attacks Multiple : 1. To be fair, it means that Big Cyclone? It's Multiple : 1. Doesn't matter if you just dropped it due to your opponent's discard effect, he now has to contend with two 4 speed mid for 10 damage attacks other than one.

Still, it's Rock Only - and Rock has two Rock Only attacks that simply rock.

Yes, that was intentional.

Atomic Drop Maximum is a 7 difficulty, 2 check throw that hits for 8, and impedes blocking. Ultimate Volcano is a 7 difficulty, 3 check attack that hits for 10 and can be made unblockable. With Onslaught, both these attacks are now Multiple : 1. That's simple, right? You don't need much momentum to fire these attacks, and they respectively will do 16 and 20 damage, without even counting any outside damage buffs!

The downside? Other cards will buff these attacks better, with better checks and better difficulties, to boot. What would be especially amazing with Onslaught is Karin's Keyword Ability with Numbers support (I'm thinking of Kanzukiryu Kakutojutsu, myself), but it shares no symbols with it. None whatsoever.

Is it truly worth the 2 CC? My final judgment says no. You have better options out there, and if you're playing Rock 3 (the only viable Rock out there), you will need a lot of cards to make him work, so Onslaught will be a great big pass.
