Thanos vs. the Sentinels of Magic

[Warmonger]

The Sentinels of Magic roster:

Sentinel Alan Scott
Dr. Fate
Phantom Stranger
Zatanna
Raven
Deadman
Faust
Ragman
Dr. Occult
Madame Xanadu
Enchantress
Blue Devil with Trident
Tempest

VS.

Thanos

The Sentinels decide Thanos is too dangerous and that they must take him down, ho holding back. They have 1 week of prep, Thanos has none (and no HOTI, IG, CC).

Fight in an abandoned city.

I think with that amount of prep and that many magical beings they could pull something off to trap him in some alternate reality/dimension or something...
