I see that the posts about SG and Rawr trolling at each other have been deleted...
Yeah, your member cards should reflect your playing style. I prefer to sap the strength from my opponents and strengthening myself; and obviously, Jellyfish prefers freeze and poison.
Jellyfish, for your member card, I think it should inflict 5 poison per turn automatically (cannot be blocked by shields like Puffer Fish), and 3 Water to use Rain of Ice on all enemy creatures (the chance of getting frozen = chance of Ice Bolt = chance of Ice Shield).
Rawr, I assume that your member card is a Spell...? Rather unique, because most people tend to make Creatures. But still, if it was me, I'd replace the "X/X" stats sign with the word "Spell", since SG didn't include the spell icon in her templates.
Another member card of mine, not made into picture yet:
Jonathan Solaris: 9/9 (20 Light)
Equinox: At the end of your turn, all your creatures gain +2/+2, and one of your creature or permanent will be Immortalized.
Solstice (3 Light): Destroy target creature or permanent.
