Many oppinion and getting more and more complicated.
I see andretimpa but what kind of duo element you think would work the best? or you think a mono element would be better?
I think
![Air :air](https://elementscommunity.org/forum/Smileys/solosmileys/../../../images/Misc/air18x18.png)
and
![Light :light](https://elementscommunity.org/forum/Smileys/solosmileys/../../../images/Misc/light18x18.png)
already have their means of bringing weapons as creatures (AW and crusader).
![Life :life](https://elementscommunity.org/forum/Smileys/solosmileys/../../../images/Misc/life18x18.png)
doesn't, but there is actually a life card that does the opposite in the forge
http://elementscommunity.org/forum/level-3-armory/living-weapon-biological-weapon/ (turn a creature into a weapon) and this seems like a better thematic fit.
If I were to place this in
![Aether :aether](https://elementscommunity.org/forum/Smileys/solosmileys/../../../images/Misc/aether18x18.png)
I would make it a duo so that fractal long sword can't be used in a mono (mostly for balance), or make this into a permanent (so that only one long sword can be played at a time and PC stops the strategy, even though it is very cost effective).
![Gravity :gravity](https://elementscommunity.org/forum/Smileys/solosmileys/../../../images/Misc/gravity18x18.png)
mono would be fine balancewise.
Another theme I though is a magical forge that brings the things worked on it to life (the theme would fit mono
![Fire :fire](https://elementscommunity.org/forum/Smileys/solosmileys/../../../images/Misc/fire18x18.png)
and
![Earth :earth](https://elementscommunity.org/forum/Smileys/solosmileys/../../../images/Misc/earth18x18.png)
/
![Fire :fire](https://elementscommunity.org/forum/Smileys/solosmileys/../../../images/Misc/fire18x18.png)
duo).
My vote would be for
![Gravity :gravity](https://elementscommunity.org/forum/Smileys/solosmileys/../../../images/Misc/gravity18x18.png)
, but I'm extremely biased
