ok here is my opinion
Minus: -10
-1 E-HERO Ocean
-1 E-HERO Voltic
-1 E-HERO Prisma (like really what do you need that for
)
-2 Magic Cylinder
-1 Skyscraper
-1 Skyscraper 2: Hero City
-1 Pot of Duality
-1 Pot of Avarice
-1 The Warrior Returning Alive (trust me, you want your heroes in the grave not in your hands)
Plus: +10, or 11
+1 E-HERo Neos Alius (cuz he's good)
+3 Gemini Spark (cuz its fun)
+1-2 Hero Blast (combo with spark and alius)
+1 Super Poly (cuz its the best DAMN card that hero duelists have)
+1 Fifth of Hope (in Heroes, its better than avarice)
+1 Solemn Judgment (Staple)
+2 Solemn Warning (Staple)
Ideas to try out
+2 Call of the haunted (for stratos and woodsman plays)
+2 E-HERO Wildheart and +2 Torrential Tribute (you got to have both of them for cool plays)
+1 Honest (for your lights)
+2 Thunder King Rai-Oh (you should know why)
+1-2 E-HERO Ice Edge (great card to get around your opponents facedowns)
+1-2 Neo-Spacian Aqua Dolphin (Look. this card is your MIND CRUSH!)
+1 Neo-Spacian Grand Mole (Great troll card)
+1-2 Mask Change (if ya want to try out the Masked Heroes, but be warned, don't ever use goka. EVER! bad card)
+1 Parallel World Fusion (try out the next evolution of fusion summon!)
Remember, these are just ideas if ya want to put these in ya deck.
For you extra deck at least run terra firma. you have ocean and woodsman so why not add him in too. He is also my favorite hero so use him right. :D also you can also try out using xyz like blade armor ninja if ya have some space. good luck with ya hero deck and duel me sometimes with it!
