Gains 1 HP per 15 combined
What does it means?
The OP may correct me on this, but I think it means that after the end of your turn, you will gain 1 HP for every 15 quanta from the water and earth elements. I assume the skill is passive and counts the quanta from both earth and water pools.
So basically, if you have 8
and 7
, you would gain 1 HP after each turn.
But on to the card, here is my verdict: majorly underpowered and pretty useless. The card's healing ability is pretty weak and makes this card only usable in a mono
deck, or duo
/
deck. Rainbow decks don't have that much quanta laying around for the heal to be useful.
The Hide ability is pretty useful on your own creatures if you are suspecting danger, but pretty underpowered against your opponent. When you think about the currently available creature control cards, this card is pretty dumb. Most CC cards or creatures just kill your enemy, or stall your enemy for several turns, comparing to that this isn't very effective.
EDIT: And why would you even want to make enemy creatures hidden? That would mean you couldn't even target them while they are hidden.
That's my two cents.
