Yes, I was pretty ambivalent about that extra slam. Agreed with leaving it off.
What about this?
Subservient to Fire (Ex?): A fire phantom is so tied to the plane of fire, that it can be controlled or banished by other elementals of the fire subtype. The other elemental attempts to turn the fire phantom as a cleric of its HD; the fire phantom resists as an undead with +2 turn resistance (?). A successful turn attempt indicates that the elemental may banish the fire phantom to the plane of fire. Alternately, the other elemental may attempt to command the fire phantom. The elemental makes an opposed level check against the caster who summoned the fire phantom; if the check succeeds, the elemental controls the phantom, and otherwise the phantom is banished as normal.
That seems a fair match to the original, but I'm not sure whether we should include it. Elementals in AD&D had a hierarchy with at least the implication that the higher rank ones could control the lower ones (although they only had rules for such in the case of elemental lords and the like).
I'm thinking it might be if the power means that if it encounters a Fire Elemental (with more HD than it?) that already has a "control elemental" type power, it automatically fails to resist if the elemental tries to control it.
