Interesting... had a similar concept with Rysa (and a couple more allies but anyway). One thing to note though, multiple Rysa's on the field can work even with a singular Fire/Earth elemental totem in the graveyard provided a similar Fire/Earth totem is in play.
How it works? Each of Rysa's power will trigger at the start of each turn. Just resolve one and put a Earth/Fire Elemental totem from graveyard into your hand. Now as both Fire/Earth Elemental totems are instants, you may choose to chain them on top of the next Rysa. Once that resolves, the totem is back into the graveyard (through uniqueness violation) and you can use the next Rysa's link to put it into your hand.
Aurastone Hammer is a bit iffy if you are running Porto in your deck as you can't target your own totems. An alternate derivation is recurring back Fire Elementals and dropping Hoxie Mettlemelt. Burn baby burn.
Some people learn, some people don't. For me, I can never correct myself to say Julia Graves as opposed to Julia Roberts
