Good Question regarding Maly cuz the synergies with him in this deck are definitely rather limited. I like him tho for emergency board clears Ancestor's Call +Elemental Destruction  or Lightning Storm. Whats also really important are his 12 Health and being potentially put on the board by Deathwing, Dragonlord , or with a Barnes and reincarnate. Then there is also some dmg potential with Lava Shock .
Maly definitely is removable as is every single big minion in this deck. Having this particular selection gives you alot of powerful turns in the late game tho, Ancestors/Maly/Storm just being one of many. If Maly sticks you can ancestral spirit reincarnate to duplicate it and lava shock for 12 dmg. ;) You could always implement the 2nd lightning storm to give maly even more meaning, you could remove al akir or kel thuzad for that, or sylvanas. The current selection of minions is really nice. The existing synergies between them and the rest of the deck are awesome! I'm quite happy with the current selection. The Plays that are possible with the 6 mana Eureka!  are really nice at turn 10, with ancestral spirit/reincarnate.

y malygos?

@FLeonidas Possible replacements for those Cards (and basically for any missing Card) are: Maelstrom Portal, EarthShock, Lightning Bolt, Jade Claws, Feral Spirit, Dr Boom, Ragnaros, Medivh, Lichking and Alextrasza. Maybe Doomhammer as well. All of These Cards, including doomhammer have been tested in this deck at some Point and did quite well. ancestral Knowledge is not so bad as well, in the current set up however I feel like it is actually not needed, the value is insane and with the Eureka theres usually some good Play available in the midgame. Try out some of These Cards, and yes ist totally fine to run this deck with a single Ancestor's call! (tested that Version out quite willingly even after having two, I prefer two of those but it is actually quite close)

Hope you try out the deck, have fun with the replacements! For those four Cards in particular you might wanna try: Ragnaros, Medivh and double Feral Spirit, or one Feral Spirit plus an earth shock. I would surely pick at least one Feral Spirit Kind of as a direct replacement for the missing turn 4 Play. Hope this was helpful! let me know how you did with These replacements, check out my stream at twitch.tv/wiebauichpylon, Gl & hf!!

You should really add Electra Stormsurge to the deck, her interaction with eureka and call is awesome, 
also, Devolve is strong right now because is wrecks magnetic and acts like a mass silence for deathrattle rogue/hunter so you could make space for at least one

replacement for : Al'Akir the Windlord , Deathwing, Dragonlord , Al'Akir the Windlord ,  and 1 Ancestor's Call :( 

In this meta ist totally fine I feel, you dont die on turn 4 like in good old pirate warrior days. doesnt seem to me you played it all that much, Maybe you had an unlucky start, guys try out this deck, ist pure fun !! taking it for a ride to legend now lol, just to prove a Point ;)

I find it too slow. Reminds me of a Big Priest deck but while that deck can go off on turn 3 or 4 your deck can go off at 4 or so it tends to get stuck there. Big Priest also has removal out the azz.
