I got my favorite team all to Level 50! emotion_yatta

Now I have 520 Moga Cash saved up from battle drops. I'm not sure which RIG to spend it on though.
I've been thinking about going for a Nisaeg, or maybe blowing it all trying to get a Kraken.
That or it might be safer to go for a galactic with prevos like Coralanthus or Ripslam.
I'm going for a water theme here. ^^;

Please vote and help me decide, I'm having a hard time picking.

I've been doing other things like catching 5x Hanzo, a Spike, and 2x Peepee. ^^;
