"the sacrificed creature" ​ when 2 were sacrificed

[Phasmoid]

On the battlefield, there is

Brutal Suppression
and
at least one nontoken creature with a ​ "sacrifice a creature" ​ activated ability

whose effect refers to something about ​ "the sacrificed creature"
and
something making the at least one nontoken creature
https://scryfall.com/search?q=oracle...rid&order=name
with such an activiated ability into a Rebel

.


To activate such an ability, a player sacrifices 2 creatures, one of which is also a land.
Crackling Emergence ​ , ​ Harmonious Emergence

Does the effect count both creatures, or just the one sacrificed for
"sacrifice a creature" ​ ​ ​ and not the one sacrificed for ​ ​ ​ "sacrifice a land" ​ ?


If it counts both, then

Would Geralf, Visionary Stitcher make 1 token each, or ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ edit: ​ I corrected the numbers here.
1 token total, with X equal to the sum of their toughnesses? ​ ​ ​ ​ ​ (I was thinking of a different card when I typed them before.)
