The Brann and Brewmaster effect that bounces a minion back only happens once because you don't get to choose a second target.

I believe if you copy the Prelate deathrattle twice it would shuffle once per deathrattle that shuffles.  So having two Prelate deathrattles should shuffle two copies of Undatakah.

What I'm curious to see is if Undatakah copies shuffled keep enchantments as well, because it's part of the Prelate deathrattle so I imagine that it would.  And those added deathrattles should count as enchantments, right?!

If they do you'd get the battlecry for the initial three deathrattles.  If at least one is Prelate's, it should shuffle with those three deathrattles still on it, then you draw and play it again to gain more deathrattles, making it six total... It could snowball to some crazy OTK if you are able to play a slow enough deck.

Would be mostly meme worthy because it's ruined if you don't get the Prelate deathrattle, but mix in stuff like Rotten Applebaum, Leper Gnome... you get constant healing and enemy face damage, plus more and more Undatakah's from Prelate's deathrattle... Immortal Undatakah Paladin!!!

It's a bit of a confusing effect, but card text is very important here. Eg, Astral Tiger shuffles as COPY, so that effect can stack, meaning you can get multiple copies shuffled into the deck upon its death. Immortal Prelate shuffles ITSELF back in, so that effect doesn't stack. Additionally, Da Undatakah combined with Immortal Prelate means it keeps its enchantments. The battlecry of copying 3 Deathrattles counts as an enchantment in this case. So if you get Prelate's effect the first time you play Da Undatakah and it gets shuffled back in the deck, the next time you replay Da Undatakah and it gets 3 different deathrattles, it stacks, so Da Undatakah has 6 Deathrattles now. When it dies it gets re-shuffled back into the deck, even when he doesn't copy the Deathrattle of Immortal Prelate this time. Copying Prelate's effect multiple times doesn't shuffle multiple copies of Da Undatakah in the deck (even when combined with Augmented Elekk), just the one. Hopefully this makes things clear, took me a while to figure this one out xd

Spellbreaker

DR Priest with Zerek, Master Cloner. 

Step 1: Leper Gnome dies three times

Step 2 Emperor Thaurissan on Spiritsinger Umbra, Brann Bronzebeard, Da Undatakah, and Baron Rivendare

Step 3: play said minions, but undatakah last.

Step 4: 12 leper triggers from rivendare and umbra for 24 damage and Undatakah from a damage spell on him dies and deals another 24

2nd, cheaper Mecha'thun!

and better in every way

So they took Princess from the Monster Hunt, and turned her into a balanced card? Hmmm. Looks nice!

So how does this work with Myra Rotspring?

Da Undatakah is not a deathrattle minion. Myra Rotspring is not a deathrattle minion. So what was the idea of your question?

 So obviously this card works in Deathrattle Hunter/Rogue. However, I believe there are 3 more far more interesting applications of this card.

APPLICATION #1; Hadronox Synergy

With Astral Tiger, you can go infinite with Da Undatakah and make infinite waves of taunts, just bait out their silences and you are good to go!!

APPLICATION #2; A 3rd Prelate

Don't you just hate that buff Paladin can't be good because of those pesky spellbreakers? Well, after your opponent exhausts their silences onto your unsuspecting Immortal Prelates, you can use the Undatakah as a 3rd Prelate, but here's the thing, he will keep his deathrattle enchantments from his battlecry, so as long as you have played at least 1 Spikeridged Steed, it can go downhill FAST for the opponent. (Not to mention the Primalfin Chamlion synergy)

APPLICATION #3; A Shudderwock Safety Net

It sucks when your Grumble is the first battlecry to be triggered by the infamous Shudderwock, but if you use Spirit Echo on just 1 minion (to ensure your hand doesn't fill up) Shudderwock can copy Da Undatakah's Battlecry and get the ability to be returned to your hand!! Of course he can be silenced, but Shudderwock will hopefully summon copies of himself after Da Undatakah triggers that also get returned to your hand!!

I think you are wrong about Spirit Echo, when the minions are dead they no longer have the Spirit Echo deathrattle. Otherwise good stuff.

You can test it with Tomb Lurker if you have it. I would but I don't want to craft it right before the expansion realeases. Let me know if you can prove it right or wrong.

Well,  #2 may work. if the keeping enchantments part is part of the deathrattle for Immortal Prelate. If that is a seperate part, then it wouldn't work. if it's part of the deathrattle, you can dump all kinds of buffs on him and as you keep playing him, he keeps getting more prelate deathrattles meaning more Da Undatakah being shoved into your deck when it dies. I don't know whether to hope it does work like that or hope it doesn't. it sounds like a fun deck to play, but it also sounds like the most aggravating deck to play against.

Yea, I believe so. And would the 6 mana 6/6 be Da Undatakah?

They might code it specifically to return itself to hand to make it consistent with the card text.

I tried with a friend of mine this interaction (with Pyros, Ice Clones and Seeping Oozeling)

Turned out that when the Oozeling died I got a 6/6 Pyros instead of a 6/6 copy of the card...

Favorite card from the set so far, crafting a golden undertakin BOI fasho

There is one more neutral to be revealed (I hope it is Rezan) but this looks like the "fun" legendary of the set.

You and me both
