No, Strange basically created a new spell to counter the shaman's curse, he just needed the blood of those 3 because they were the descendants of the shaman.
He said in the third panel that he will empower Thor team with his spell similarly to the Curse.
He never said that he will curse or use the same spell that the shaman did, he only said that their blood will empower his own spell.
He was able to bypass the curse, his potion helped Thor and his team to defeat the undead vikings.
Thank you, for providing an evidence that Strange didn't cursed Thor and his team, he only used their bloods to make a spell of his own, and thus creating the potion that was able to bypass the curse of the undead vikings
Do you have issues reading English ?
I think you're the one who has issues in reading english, the panel clearly stated that the blood will empower Strange's own spell, he never said that its the same with the spell that the shaman used.
He is saying that he will empower Thor's team similarly to the Curse and even confirm in the next page that his spell will not have drawbacks like the Old Man because he is a pro...
You're dense lol, he never said that it was the same as the spell that the shaman did, he only said that the blood will empower his own spell like the shaman did with his own, did Strange said that its the same spell? or similar spell?
You don't understand the meaning of "countering" and "bypassing", that's painfully obvious.
I do understand, the potion bypassed the Curse. no amount of headcanon of yours will change that.
The only thing that was debunked here is your claims
