Interesting, so
Freeze it and it goes to the enemy's side of the field? So it would leave you if
you attacked it, haha.
Apart from that, in terms of strategy, you would probably
Relief to buff your creatures and then send it to your enemy? In that case can Relief send the attack of Fume Being | Steam Being into negative numbers?
I would also like some sort of art to be given to this card, and as for the name, it reminds me too much of Steam Machine. Might I suggest Water Spirit?
