Swapping creature and weapon simultaneously seems like a good 
duo card
maybe something like:
Speaking of which, would be another good element for this card's ability... unfortunately, trident already has dibs there.
definitely works for the card as you have it, but for a fish that turns itself into a weapon and back i dont think its the way to go
How funny I was thinking of this exact same card~
Quetsions:
Why would you ever want to move it into weapon slot and sacrifice your weapon slot when a better weapon is there?
What would happen if a crusader endows it, can the crusader move into my weapon slot, then another crusader endow that crusader and move into my weapon slot?
The main problem is that weapons are supposed to be more efficient than creatures at damage dealing. Why would someone want to sacrifice their weapon slot merely to give some soft CC protection to this?
you wouldn't in most cases, hence its a "free" ability that doesnt increase the cost of the creature. it could make for interesting interactions though
huh didnt think of that... crusader endows it and becomes a weapon, its ability remains as Hand. another crusader endows that crusader and gains Hand and the first crusaders stats.
reminds me of the spell card i made to turn a creature into a permanent, the mechanics are different but the gist is the same.
Living Weapon? saw that card a while ago and liked it, but it didn't really inspire this card. just thought a swordfish would be a cool card, and went for the name pun for the ability.
Is the weapon's damage increased if the swordfish has been buffed beforehand by SoP? I could see dropping other buffs, but thought perhaps an exception might be made for SoP because of its synergy with water.
a special exception for one card doesnt really make sense, however, i think just letting buffs remain (all buffs, not just stats) might make for something more interesting than the present form. don't think weapons can have both momentum and an ability though...

I can think of an interesting use for it if transforming into a weapon simultaneously animates the current weapon. Then you could use it as a roundabout AW on a stick.
E.g. with 2 of these, you could animate 1 weapon every turn.
i.e. Play weapon, transform first, end turn. Next turn transform fish back to weapon, play new weapon, transform second fish to weapon... rinse and repeat 
a good idea for a card, but don't think it fits the theme as is. unlimited animate might cause balance issues in the game as well, as weapons tend to be more efficient than creatures, AW requires card space as well as limits how many weapons you can have at once. look at the cost of crusader, which doesn't even truly animate a weapon.
