The Enchantress and Executioner has MASSACRED Thor on at least....3 occasions.
They never beat Strange, but they did well against him because Strange ALLOWED (CIS) himself to be kissed by Enchantress, which sapped his power(PIS) making him weak. He allowed her to do so because he knew they were up to something....he even said "It's better to have evil under foot than over head", just as the Ancient One said about mordo. That fight is totally moot.
Oh, and Strange is what Loki dreams of being when he grows up.
On to this fight.
Thor can indeed absorb magic energy, but never once has he been capable of absorbing spells. Dr.Strange hardly ever blasts simple magic energy in a fight unless he fights other heroes(otherwise he'd destroy everyone with too much ease).
Bloodlusted Strange won't do that, nor would he hold back and only use white magic.
Thor is also VERY susceptible to magical telepathy, which Strange has in spades, he's above Xavier with his Eye.
Strange has a spell which can steal Mjolnir away turning Thor into a simple strong man....who can be banished.
Nearly everytime Thor and Strange team up, Thor is in the position of student and Strange is the teacher, it's obvious Thor isn't as learned in the use of magic as Strange. Strange went as far as saying "I'll handle the hocus pocus, you just go hit things with your hammer."
Strange's shields can handle ANY attack Thor uses on him, Strange has taken full on world destroying blasts and blasts from Galactus with little effort. Thor, on the other hand CAN'T handle what Strange brings to the table.
This fight could be over in a 6 word black magic spell:
"Satan, take him, he is yours!" and bam....Thor's soul is in hell and Strange takes a nap. Simple as.
Or Thor is wrapped in a cyttorak bubble and dies. Or Thor is attacked mentally. Or Thor is turned into a table....seriously, Strange can do it. He has no rules to what he can do, Joe Quesada said so himself:
"Strange has no rules to his universe, he can do anything....there is no real threat to him because he can simply caste a spell and it's all over. How can you kill someone like that? How can you kill Strange?"
This fight wouldn't be a curbstomp, but Thor loses 8/10. With a half second prep, this would be a massive curbstomp.
