My mistake then, I thought I watched a video where the weather overruled the buff. I could be confused.
It will once weather is played last. But then once weather is cleared ur units will be reseted to their original value so buff will be gone as you said already.
Ok so i havent found a specific scenario like you said in my video but i found something like this:
https://www.youtube.com/watch?v=FDwGRq57CRg starts from 36 min.
If weather + clear weather resets buffs than i need to reset debuffs as well. I'm almost 100% sure it works like that with wounded units.
Oh i found something else, starts at 1:43:10, you got there those mahakan guards which are buffed and wounded than weathered and than after the end of the round when weather is removed from the battle field they both go to their original value which was 4STR. And yes i know i could use weather first and than scorch those guards with zoltan
Theres something interesting at 1:48:30 also i looks like once weather is played and you got some dwarfs on the table than once you play dwarven mercenary into the weather it will affect only its original value but not the buff from dwarves. But i'm pretty sure that i would affect the buff if weather would be played later. So its all about the calculation order in some cases.
I got a question here also. If ill play a 3STR card which get +4 STR everytime some1s plays a special card, and there gonna be a higher value unit on the board and after that ill play a scorch which is a special card what card gonna be removed? Lets say the other card is 6STR so will my scorch destroy his 6 STR and than buff my 3 STR to 7 STR or it will take out my buffed card? I think the calculation order is like special first and all the buffs/debuffs etc are calculated at the end of our turn, thats why we got that coin flip animation even if some1 will pass, so the game got a time to do all those calculations etc.
