Young starfish is kinda useless at 2|3.
I assume that Old Starfish pays 1
everytime it adds a "regen counter" to yourself? I think it's slightly overpowered--you'd start seeing it in speed rainbows, and you can make a duo out of forest spectres and that which would be so cheap in terms of quanta you could splash
mark for explosions or
mark for unstoppables. Dunno if you can get a fractal Old Starfish deck to work.
I kinda dislike the art--the starfish is too pink. If you've ever gone diving and seen those sprawling orange and white ones, you'd most probably have chosen them over this--they're more majestic. Also the orifice is too obvious which is a little gross.
