Ive never built a H20 deck, however there is one card u might think about, Metallizing Parasite - Lunattite. You can pull it with Grizzly, and its nasty if played right.

Minus one Salvage, good card, but sinister takes care of that alittle.

If you have trunade i would recommend a swords and possible 2x area b's.

toss your Nightmare penqiuns for another Mobius, and for something alittle funkier .... like ... Abyss Soldier. Which combo'd with Sinister Serpent, has a SMALL but decent lock.

my thoughts, but ive never built a h20 deck and im a noob.

i would use Abyss soldier but i aint got any so thats what my Penguin Soldiers are for
