As some before me, I would like to post my looooong buff/nerf list:
ORDER
Trigon:
You can have only one double aspect. If you play an another, then the old one gets destroyed.
This way you can't just double aspect everything, if you want to have the best cards of an aspect (they should be the ones with at least 2 levels of the aspect + 1 or 2 generic), then you have to invest in more.
This might not change that really much, but it would certainly make Trigon weaker.
Almaric:
(Maybe) 3 turn cooldown, you can choose the ability to be active in your turn or you opponents turn, not both.
I think Almaric got nerfed too hard, I hardly seen any of them after the nerf.
Prosperous Ruling:
(Maybe) If I remember Fuzz said something like it could summon a milita at the start/end of your turn.
WISDOM
New Horizons:
2 mana W, Blessing, Legendary
Choose a shrine, this blessing will give 1 level of that (choose any color in case of Trigon).
Completely removing/reworking New Horizons would destroy plenty of decks. I think with it ramping once is ok. What is really annoying is if the opponent plays 2-3 NH and you play 3 mana behind.
With this, decks still could have a good start by ramping one early, but it would be a lot more *expensive*, since if you want to start good, you have to have 4 NH, and after the 1st, the rest is useless, and it could be destroyed by spell destruction.
Maybe making it a blessing, so it can get destroyed all the time, is too much, maybe it is enough if somehow you can only play it once.
Or maybe it wouldn't be legendary, only a blessing, so it can be destroyed.
Timea:
2/3 >> same as now, but give only 1 might emblem to something, maybe can't even give it to herself.
I think being a really strong creature, assisting other creatures, and drawing 2 cards is too much. And she can use other might emblems for card draw as well.
Parallel Evolution:
Remove card draw.
I think it would be plenty strong without it too, just maybe not an autoinclude.
Silencer:
Costs 3 mana (like all other aspects' 4 level blessing things), has 4 energy.
I know it is "not OP, it just seems like it", but newer players won't really understand that if it's not OP, after it is played why do they lose 90% of the time.
It is the same as now, but for cheaper and the opponent still has to pay +1 mana. But at least now usually it can be destroyed by playing 2 cards into it, when the current one quite often needs 3.
Library Guards:
Costs 3 mana
Have an ability: 1 mana: draw a card, stupefy Library Guards.
This way it is not a 4 mana card, so maybe it will be playable again.
Sunborn Subordinate:
Same as now, but 3/3 >> body
It was never really used, then out of the blue it just got nerfed.
Foundry Engineers:
3 mana WX, starts with 2 energy.
It would be more expensive, but it would actually do something when entering the field.
Crazed Apothecary:
Same as now, but 2/2 >> body
So occasionally artifact decks will include him too.
NATURE
Haldiri Rider:
3/3 >>>, 4 mana NN, Swift
It is not the 2/3 >>> creatures' meta anymore, so it could get it's old glory back. It is probably still quite powerful, so it is double nature level, so it won't get included in every single deck.
Moonlight Patrol:
+1 SP in opponent's turn
Some people suggested it before, it patrols at night, in Spellweaver probably the opponent's turn is "night".
Primordial Treant:
If there is anything is under it, it gains +1SP (only +1SP, so up to 2SP, no matter how many elves are under it).
Elf Commander:
(Maybe) Zzz: Give an another creature +1 SP.
Haven't seen this card played in ages.
Nature's Encouragement:
REWORK
Birchwood Invoker:
REWORK
RAGE
Detonate:
(Maybe) Deal 4 dmg to creatures with target emblem.
Maybe target emblem decks would be more playable.
DOMINION
Prin'ha:
In DDX mode only get +1SP not +2
I know she's not op, but she is a pretty okay card. Why would she just casually get up to 4 speed? 4 speed is supposed to be *special*.
Skatador's Bidding:
REWORK
Rhygon:
(Maybe) You could choose if you want to summon or not, maybe make it cost 4 mana and/or 3 aspect.
Honestly I have never ever seen this card in play. It is probably because I wasn't too active when Dr. Sticks was broken, but still it was only played because of that.
