I know the existing legendary protection sees only what is in your collection. Of course you need all legendaries in a set to test it, so I understand why it is not common knowledge, but if you do have them all and dust one you are guaranteed to see that one as your next legendary.
It can be exploited to try to get a specific golden legendary (I did this for Lord Jaraxxus) but unless you are very lucky it is more useful as a way to fill in nerfed cards.
Now, this doesn't prove it won't work as you suggested for other rarities, but it should be quite quick and safe to test that when it comes into effect.
That's certainly not what happens with legendaries. I once rigged getting a golden Lord Jaraxxus by dusting him when I had all leg.s in the classic set, then as expected the only leg. I open is the old Lord J. (I was actually hoping to open him in a golden classic pack. I didn't, but got super lucky with him being golden in the very next normal pack.)
In any case, with commons it is easy to test because you usually get them all way before finishing opening packs, so you can expect to see them again at some point anyway.
Basic cards can be disenchanted once they HoF'ed. They got their own rarities after HoF (Common). And then you can dust both copies of regular and golden (If you already have it by leveling your Priest Hero).
I've done it before, but I forgot. (Year of Dragon perhaps)
Mind Blast was one of em. (From Basic to Common Rarity)
This seems like a cheap way to have a solution for all of the busted but low mana cost cards in this expansion, with it being at four mana. You kill the opponents 4 mana obiwan kenobi they coined out on turn three, and they top deck the ghost of obiwan kenobi which is more powerful than you could possibly imagine, and you play this to banish it to the shadow realm until you can deal with it on a higher mana turn.
Make Avalanche deal 3, Ruination cost 8, revert Rhasa to 7, Black Spear cost 1, Get Excited cost 2, Culling Strike cost 2, Noxian Guillotine cost 2, and you might have a fair patch.
Reverting Rhasa to 7 = It is nerfed because it is used as a finisher in the decks which you are whining right here = All of Shadow Isles Aggro decks. It should stay as 8-cost and it is still useful in control decks. It is only a bias that Rhasa the Sunderer is a bad card. You think that because it saw a nerf. It is just a prejudgement. The card is ok in control lists and just bad in aggro lists right now. Don't misjudge the card.
You might consider that all cards might be part of other archetypes. Reducing the cost of cards like Black Spear, Get Excited!, Rhasa the Sunderer will harm control, not aggro. You might consider that Aggro decks may use those cards too. That's why Black Spear and Rhasa the Sunderer has been nerfed. That's why The Rekindler has been nerfed twice.
There are some problems about the game, Everyone's aware of but your solutions other than Avalanche makes more powerful what you think you reduced its power. Avalanche even is a good state right now.
There are other problems. Some buff cards shouldn't be burst spells for example or some keywords are problematic right now. The game needs more mechanical changes than single card nerfs. I always supported this on this forum, on reddit, on official forums etc. Everyone says that "no, some cards need nerfs". Those cards are nerfed and there are still same problems. I insist on what I said before. The game needs some mechanical changes as rule changes like how elusive followers will lose their elusiveness, low-cost fearsome units are problematic so reduce its requirement to 2 attack instead of 3 etc.
Single target nerfs won't make the game better unfortunately. It is just because of Spell mana. If you want to keep spell mana in the game, you need to tinker some other mechanics to reduce the power level of Aggro. That's obvious. Even more obvious with 20 Nexus Health. I really wonder when Riot will realize this.
(Apparently there's no working Quote function. Just opens a page of code.)
"This one is quite bad as it could turn many high cost followers unplayable"
-- Did you miss the word "conditional"?
"Hell, even aggro decks can tech in a few control cards and see their winrate increase if all there is are aggro decks."
-- I don't consider it creative or even substantially varied deckbuilding to toss a combat trick in an aggro deck. Big whoop.
"This game is getting better and better with each patch, Elusives and Fearsome units were impossible to dealt with when the game first launched."
--Culling Strike is the entire list of low-cost removal against low-cost overpowered threats. THE ENTIRE LIST. Black Spear is now a bad Get Excited, and Get Excited is a bad gimmick card for an undersupported unreliable garbage archetype. Discarding stuff is always inherently going to be a trash archetype because an empty hand means you have no ability to interact in the game. And heaven forbid it's Ionia and they play a +1 Attack mentor guy on their 3 Attack card like Zed, or it gets a +1/+1 Hawk buff. And even calling Culling Strike an "answer" is generous. Eating 3 from Zed, Elise spawning a Spiderling, other cards being outright immune to it, or having to burn it on a non-champion... the list goes on and on for what is wrong with this exchange. I have to play an expensive conditional card with no intrinsic value and it doesn't function in many situations and doesn't even answer in others.
What is this long list of mythical answers to this overpowered non-interactive garbage, of which you've provided literally zero examples?
"It's kind of ironic how a game that was built on the idea of constant back and forth and interactive gameplay is plagued by decks that circumvent that exact principle."
-- Indeed. So many early game aggro cards are overpowered to an insane degree and then they have the audacity to nerf one of the few BAD CONDITIONAL ANSWER cards. What's worse is seeing people celebrate that because they're mad at Elise Autofill decks... so let's celebrate nerfing 50% of the early game responses to Elise. Like, really? People who hate Elise Autofill (now with more Kalista) should be frustrated one of the only answers TO Elise got nerfed while she remains overpowered.
Make Avalanche deal 3, Ruination cost 8, revert Rhasa to 7, Black Spear cost 1, Get Excited cost 2, Culling Strike cost 2, Noxian Guillotine cost 2, and you might have a fair patch.

one would assume as much yes.

meaning this will work as a Silence effect for things like Edwin, making it a 2/2.
this also means for cards you have you want to protect or heal this effect works.

If you have the dust to, then yes. It is a lot less risky than it feels.

Yep, fuck me plenty..:) Anyway, I am still waiting for Demon Hunter Naxx cards:)
New Neutral Minion - Maiev Shadowsong
Yet another tool for aggro decks (and yes, I am looking at you demon hunters) to get past a big taunt. I am not sure, how I feel about it.
To be honest, I would like a spell or battlecry minion, that activates all dormant minions immediately.

Just to be sure, if I don't own neither Leeroy or Velen I should craft them BOTH golden, right ?

She's also a super-freeze effect for control decks to buy 2 extra turns for answers. I fully expect Maiev to be almost Zilliax levels of play rate.

Very interesting effect that is going to find a lot of cool interactions.
This patch makes me want to quit this game.
Making Avalanche to deal 3 = ok
Making The Ruination to 8-cost = meh
Reverting Rhasa to 7 = It is nerfed because it is used as a finisher in the decks which you are whining right here = All of Shadow Isles Aggro decks. It should stay as 8-cost and it is still useful in control decks. It is only a bias that Rhasa the Sunderer is a bad card. You think that because it saw a nerf. It is just a prejudgement. The card is ok in control lists and just bad in aggro lists right now. Don't misjudge the card.
Making Black Spear to 1-cost = broken
Making Get Excited! to 2-cost = broken
Making Culling Strike to 2-cost = ok-ish, but might bring some other issues.
Making Noxian Guillotine to 2-cost = breaks some synergies (aka. Heimerdinger)
You might consider that all cards might be part of other archetypes. Reducing the cost of cards like Black Spear, Get Excited!, Rhasa the Sunderer will harm control, not aggro.
