G6
In the Alchemical Tarot, that you like, the meaning is more positive than in the Rider-Waite.
10 sticks are joined into a bonfire where a phoenix arises; this stresses the renewal.
Here the card doesn't only say there is a burden. It says that we can get out of a difficult situation and to reborn stronger.
With regard to a relationship I don't know exactly, this depends very much on the context, but with the Alchemical this card says that there could be a burden or something heavy, but from this something positive is possible through a renewal.
I do like all the wand cards in the Alchemical because of the fire! Yeah, I think there's a case to made for the experiences of the past giving birth to something different and hopefully better in the 10 of Wands. I looked at the image from the Rider Tarot and there is a house or castle in the distance. Having just noticed that little pictorial element it supports the idea that the person is using what they have/know to build something. This idea is more in the picture in the Witches Tarot, but it is in all three decks Alchemical, Rider, Witches and I'm sure others. The person doesn't look burdened so much as they are determined/strong/capable. They aren't dragging the wands, they are holding them off the ground and marching forward. This takes strength, endurance, purpose.
