Pros :

Spawnpoint, swarm creatures, can eat up attack spells, gets mana of creatures level when a creature is destroyed
Also i favor over libro which can just be dissolved
Zombies - resilient and the enemy mage will always trigger bloodthirsty
Cloak on turn 2 prevents early rush of attack spells and gives you more time to react to opponent
Wispwillow gives you the exra mana at the beginning to be a little more vesarile if needed
If they focus the graveyard get them with creatures
Deploying crawler and venomous first usually will get some hate allowing you to do more of what you want
Cons:

Druid can deploy from a vine anywhere, including tanglevine which bloodthirsty is useless againt. Also making it to the tree takes forever.
Zombies move slow so you need some movement spells and/ or walls
Lady beastmaster can be in your face fast so cloak can be obsolete
Flyers move around zombies so plan for that, maim wings, gravikor, another flyer, or knockdown
Bloodthirsty can limit what you can do since zombies are stuck in a zone with a damaged creature
Burns and acid ball do direct dmg to zombies
Necro mirror match

Hope this helps

Im a big fan of graveyard wispwillow t1, t2 deploy crawler then cloak of shadows and death ring, t3 deploy venomous zombie and cast minion then deploy a creature every turn or so.
Cloak lets you keep your dostance. If they close then your creatures have less diatance to walk. Deploying a crawler 1st  can be a distraction for a creature or mage. And venemous next makes them want to kill it fast. It can soak up attacks and eat up creature actions.

I dont follow. I thought you were referring to just having another zone to deal dmg to trigger bloodthirsty.

Ahh i see. I didnt watch the show much so i dont remember too much

At first glance it doesn't look like the "mermaids" will he doing the killing.

Also, I'm curious as to whether you'll find that two shallow seas are enough. I'd personally run at least three. Please let me know what you find on this.

I am also a huge fan of lullaby and I've found limited use with song of love. Your mileage may vary.

Since you plan to start with Naiya, about what turn do you think the water elemental will hit the arena?

Its a quote from the song murmaider. I just ran with it lol. I agree though.

And dropping a song of love for another sea wouldnt be too crazy and would work. Is song of love worth it of you can just sirens call your target? I know the love token can be put on your own creatures but looking at it now sirens call would seem to do the trick, thoughts?

And the water elemental, honestly im not super crazy about him.  6sbp and 22mana i believe - huge investment.  I originally wanted 1 of the undead pirates, turghut or blightheart and may switch to one of them. If i do then it frees up a few more sbp.

shallow seas' are cheap(mana and SBP), I wouldn't take less than 5. Half the arena ocean is where it is at

Idk if i would go that far but it seems like a fun play.

Sorry again abt not having this in an octgn sbb thats easy to read, im still having issues with octgn atm :b

But, this is my 1st attempt at a siren and im stepping way out of my comfort zone with this lol


Probably start with naiya and shallow sea on turn 1.  i havent put a whole lot of thought into where it goes from there. 

I realize the songs and bloodthirsty are pointless against a necromancers creatures but this is my starting point.

Any feedback is much appreciated!

I will not disagree with any of that lol.

I personally think surging wave and flameblast are better as well.

And the change of attack spell might make the next iteration.

I think blind would be a fun spell to add as well

Thanks man!
Yeah, rise again was useless for me at the tournament. 

And good catch. I fixed it. It was wispwillow
