With Aura Drill out, that's a possible 5 life. I tend to see Android 18 Black pack 3 of these suckers with 3 Android Attack Drill for a freakin' 3 times energy attack doing 9 lifecards of damage each. It's weak to start out with, but getting some + lifecards of damage drills on it increases its viability. Just make sure you have cards that raise your power stages after this card drains you out.

Or, you can use it, with a card like Cell's Arena, to do moderate damage while lowering your Main Personality closer and closer to zero to use your allies. In a straight-forward beatdown deck, this card does not work very well, since you really have to lay it on thick right off the bat to catch your opponent off guard. Plus, without a lot of power stages, you might not even be able to fully use this card's potential. I know this card will do big things in future sets, but right now there are much more powerful energy attacks, and much more efficient means of lowering yourself to 0. 

Ugh. That's the first thing I thought when I saw this card. It can be really good... if u have the power stages to use it like u can. It can be played 3 times in a row... but it costs 2 power stages each time... however, throw in a Black Energy Stamina Drill and u can have fun with this one... >_<

the only drawback about it is that you still have to pay 6 stages, but that can be curbed by orange mastery or by focusing. To top it off, its a tien card, meaning you get to use it for tien's flight.. which is a nasty enough combo in itself, so its a staple in a tien deck.

As for tuff enuff, since it gives tien decks a boost, thats great for tuff enuff, since tien decks are often more effective when they only have to worry about survival victory.
