Well, I'm lazy and don't feel like opening 36 million windows to show you Piccolo's power *hypnotic waves cover the area making everybody believe that it is just a technical difficulty and not laziness*

Besides, Pojo has the card posted ;/

Now, we have a 7 for 1 unless you use this when Piccolo is at 1 above, changing it to a 1 for 1.  Of course, that is great.  Amazing damage to cost ratio.  Then his power...  Let's just say that in a perfect world, Piccolo would not have been released with such an amazing power and such high base since it could possibly unbalance the game that has already been hinging on Saiyan Team.  Note to Score, fix the problems, don't replace them.  What am I getting at?  The fact is that Piccolo doesn't really balance the environment, he merely replaces the Saiyan Team.  But that is off subject of his power which, suffice it to say, is sick.  Black Charged Ball anybody?  You love that PUR of 5?  Well, I like it being 0 better.  GG.  Piccolo's Fusion?  As if Happiness wasn't enough for infinite stages.  Paid Off?  Okay, I'll make my Happiness give me 9-12 EVERY TURN.  Piccolo's Special Beam Cannon?  Sick...  This wouldn't be so bad if you played the card and had to wait until your turn to use it again.  But thanks to the refocusing rule, you can refocus with his power and pull the top card anyways, saving your lock or combo.  Too many combos to make this personality too good. 

Should you run it?  Depends on if you want to wait on the equally as sick Broly to be in the 40% that will use him, or if you want to be in the 40% that will use Piccolo.  Just realize that this is the new Saiyan Team leader...
