Wailing caverns. Bug or intended?

Yesterday i was testing out my new gonk druid deck, celestial gonklignment when something weird happened. I had anaconda on board and played celestial alignment and all the nature spells in my hand cost one not zero. So I said, okay it works this way I shod have just played her after alignment" but then every nature spell I drew was zero mana just the few I had in my hand when I played alignment weren't. 

Bug or working as intended?

The description does do what was written correctly, "set the cost of cards in hands and decks to 1". Anything that reads 'set' would completely supersede the cost reductions, like how wondrous wand would set cards to 0 even if the card was affected by Boompistol Bully or Loatheb.

I would say that everything is working as intended.

I disagree, Anacondra is a permanent effect so it should not work that way
but I'm not willing to argue about hearthstone weird interactions & should doesn't always = does :p

I agree that it should be a permanent effect. If you play a Raid Leader  it still buff minions you summon before and after you play him

This is a known interaction between auras and set effects.

If you have an aura up that sets a specific costs and then play a card that would change that cost it will overwrite the aura for as long as the card remains where it is (in hand for instance).

This is what happened to you. Anacondra reduces the cost of nautre spells by 2, but then Alignment overwrites her effect and sets the spells in hand and deck to 1. Since the cards in your deck entered your hand afterwards and Aura effects don't apply to cards in the deck the Alignment effect now gets overwritten by Anacondra.

It's not intuitive, but it is consistent.

If you have a 6 mana Nourish in hand and play Lady Anacondra, your Nourish now costs 4. If you cast Celestial Alignment now, your Nourish will now cost 1 because you discounted the card costs first, and then set its cost to 1. You basically set the cost of a 4 mana Nourish to 1. The cards that you drew afterwards had their costs set to 1 first by Celestial Alignment, and then their costs were reduced by 2 (because Lady Anacondra only affects cards in your hand after you draw them), reducing them down to 0. Hearthstone doesn't recognise the original mana cost of cards you cast, only the mana cost you paid. This is why if you cast Deck of Lunacy after casting Incanter's Flow, your 5 mana spells will only turn into 7 mana spells because they were discounted to 4 first, and then transformed by Deck of Lunacy. There's also the Wondrous Wand interaction mentioned earlier. This may not be the most obvious interaction, but it is logical. The Raid Leader counterargument doesn't make sense becasue you can't compare the interactions of a minion's attack with the interactions of a spell's cost.

There is only one excption that I can think of that isn't really an exception at all. Remember when Naga Sea Witch broke wild with giants? Playing her would set the cost of all the giants in your deck to 5, and since the discounts only applied once you drew the card, you'd basically get free 8/8s. This is in line with what's stated above. It would also mean that giants that are in your hand when you played Naga Sea Witch should also cost 5 regardless of the discount they had before, but as can be seen from this clip the giants in Kripp's hand costed 0 or 1. In this case, the giants' discounts are being applied after the cost change, which is the opposite of the [Hearthstone Card (Incanter's Flow[Hearthstone Card (into Deck of Lunacy or Lady Anacondra into Celestial Alignment interactions suggest. My assumption to the reason behind this is that the giants' discounts aren't aura effects like Lady Anacondra's, and therefore there is a different order of priority as to how cost changes and discounts are applied.

Edit: Not sure why I'm getting a bad card name error.
