Who would win: Ahzek Ahriman of the Thousand Sons (W40K) or Tatsumaki (1PM)

[controversial-me]

Both of these characters are powerful. Both are considered as sorcerers/psychic's (to grossly summarize) , but who would win in a fight?

Here is a quick rundown of these two characters:

Ahzek Ahriman -~5000 y.o- from Warhammer 40K:

-A very powerful sorcerer and former member of the Thousand Sons legion (he was exiled due to a magic ritual gone "correctly" cuz it technically worked) .
-He possesses immense psychic abilities.
-Can control time, reality, and manipulate minds with his magic.
-Wears the Black Staff of Ahriman, which enhances his powers even further.
-Has extensive combat experience and is skilled in hand-to-hand combat and with a variety of weapons (as expected from a W40k character).

Tatsumaki -28 y.o- from One Punch Man:

-One of the most powerful heroes in the One Punch Man universe (She is an rank 2 S class).
-A powerful esper who can manipulate objects with her mind.
-Has immense psychic powers, capable of creating telekinetic barriers and lifting large objects with ease.
-Can create powerful whirlwinds and control the weather.
-Physical abilities include immense speed and reflexes
-Possesses great psychic strength

Flatsumaki will lose. Not only can she not stop time, she's also flat!
