I would like to clarify some points here, and also say why I feel these changes are coming.
im not critising these changes, or praising them. I don't want to do that until I can actually play with them.
When we are talking about remembering strength, and remembering buffs and wounds, that isn't actually as confusing as it sounds.
lets say you have unit at 5 strength
swallow potion it to bring it to 13
weather it and it drops to 1
what the game will remember is simply to add 12 the this unit when the weather is cleared.
it doesn't actually matter what buffs or wounding has occurred once the weather is played. All that happens is that the current strength will go up by n-1 where n is the value of the unit before weather. (In this case 12)
So your unit now at 1 strength now gets buffed by 4
it goes up to 5 and then is wounded down to 3
when the weather is cleared the unit will be at 15 strength.
---------------------------------------------------------------------------------------------------------------------
Another point I think should be clarified is about clear skies.
This change I think is necessary to balance the weather cards based on their colour.
Note when I am talking about 1 row, I'm talking about 1 row for both you and your opponent.
1 bronze weather card only affects one row
so it seems necessary to make clear skies only clear one row, it is a bronze card
1 bronze = 1 bronze
2 bronze clear skies are therefore necessary to clear 1 silver weather card (white frost etc...)
2 bronze = 1 silver
3 bronze cards are needed to completely remove the effects of ragh nar roog
3 bronze = 1 gold
aeromancy doesn't quite fit in with that, however aeromancy is silver because it is the choice of 3 bronze in one card.
--------------------------------------
Now I will do some pure speculation here:
i very much doubt that clear skies will only have a form in a bronze card.
I think there will be silver and maybe even gold variety cards that have multiple row weather clearing effects.
it wouldn't surprise me to see alzur's double cross get a silver quality clear skies effect.
and that would make sense with what I described above.
First light (bronze card)
rally - pulls a random bronze unit
clear skies (1 row) - counters the effects of 1 bronze weather card
Theoretical new double cross (silver card)
pulls highest unit from your deck, can be silver or bronze
Clear skies (2 rows) - counters the effect of 1 silver weather card, or two bronze, or 2/3 the effect of ragh nar roog
and who knows, we may see a gold variation, that follows that pattern.
(I don't think it would summon gold units, but still have a balanced ability)
-----------------------
Hopefully this clarifies things for anybody who was either confused or unsure with the proposed changes.
i have done my best to outline why I believe these proposed changes are coming (if they are)
We'll have to wait for the next patch to find out.
