Well, technically it's not little city because this deck has nothing of the control aspect associated with that decktype, which is what makes little city little city. Just at a glance, the Tomatos are an obvious drop here. You don't need them for tribute fodder and their overall usefulness is questionable at best. Sure, you can get your reaper or sangan a bit easier, but neither is really integral to your strategy. Also, Oversoul is not particularly hot here. Getting extra bodies on the field is nice, but a 1900 Atk vanilla really isn't much to be calling home about and that's all Oversoul is good for recurring here. I also question the usefulness of adding so many of the cards in full copies. Your big thing with this deck is using Ocean to toss the same monsters at your opponent time and time again; holding multiple copies of the same stuff when you can only deploy one at a time anyway is not that appealing, so I'm going to suggest cutting down your monster count in favor of more support and some extra search that should - hopefully - improve your chances of getting whatever hero you need in spite of running fewer of them. This is a decent gameplan, yes? Then let's get to it. :3
-1 E-Hero Captain Gold
-2 E-Hero Neos Ailus
-1 E-Hero Wildheart
-2 Foolish Burial
-3 Mystic Tomato
-1 Mystical Space Typhoon
-2 O-Oversoul
-1 Smashing Ground
-1 Spirit Reaper
+3 E - Emergency Call
+3 Kycoo the Ghost Destroyer
+2 Lightning Vortex
+3 Royal Oppression
+1 Snipe Hunter
+1 Solemn Judgment
+1 Ultimate Offering
So yeah, as you already observed, Emergency Call certainly trumps Tomato in usefulness any day, and with three copies 7/40 of your Deck is a practical Stratos, which should be quite sufficient to help you open most of your games with that starting play of choice. As much as I'm a fan of Foolish Burial, I don't see it being particularly useful for you here as it's really just getting you stuff to pull back up with Ocean, which you should really be doing with more beneficial discard effects or the courteous assistance of your opponent, and you have plenty of search available to you anyway. In most cases, Emergency Call also amounts to the same thing as drawing any given e-hero you've got, so maxing out like this is not all that beneficial for you considering your lack of special summoning options. One Ailus is quite sufficient, as Stratos, Gold and the D.D.s (not to mention a certain other addition) can already provide you with a good deal of bulk, not to mention that Skyscraper makes the whole thing a lot more dangerous for your opponent in the first place. Two Wildheart should also cover your trap-resisting needs quite well when backed by the powerful search and recursion and you usually don't want many Golds hanging around your field as they render you a bit too Skyscraper-dependent. One is sufficient for your field search needs and can be pulled back up by Ocean should you run into something really big that needs to have its face smashed in.
Anyway, I'll advocate not maining Typhoon here as your should - in most cases - be using Stratos for any S/T removal needs anyway. Feel free to side it if Skill Drain worries you. A single Smashing Ground is also not going to do you much good on the removal front. Considering the way this deck generates free cards for you when it gets going, you should have no problem exploiting said free cards with the far more widely destructive Snipe Hunter and Lightning Vortex. Kycoo, despite looking rather off-theme, can actually render a number of valuable services for you as well. First and foremost, he keeps your graveyard safe from disruption. Considering that this is where you will be pulling your free cards from, that is huge. Secondly, he's muscle, big muscle that helps you maintain field dominance. And finally, he can mess with your opponent's yard while smashing face in the process, disrupting any opposing graveyard strategies that try to rival yours. He's non-searchable in this deck, but still a card you'll probably be happy to see more often than not.
Finally, Royal Oppression is a no-brainer choice here. (another reason why Oversoul needs to go) You have no real special summoning options available to you, certainly not anything that would come close to what a deck dedicated to such things could set up, so it's far more beneficial for you to shut them down altogether and make your hero hoarding that much pricklier to deal with. If you have multiple e-heroes (preferably one Ocean on field and the other in hand) hanging around to your opponent's one monster and Skyscraper and Oppression out, there are really very few monsters your opponent can play that you can't counter with a simple Ocean recursion and Skyscraper-backed counterattack, probably dealing bigger damage in the process than your opponent did. Ultimate Offering is there to offer a bit of an offensive edge (the only form of swarming that completely circumvents Oppression), allowing you to set up big S/T wipes with Stratos and pounce on a weakspot to seal a quick win for yourself. A third Solemn helps keep Oppression and Skyscraper around and provides assistance in pushing through your big plays or countering your opponent's, whichever the situation calls for.
So yeah, there you have it. Though this monster count might look rather puny, keep in mind that the practical amount of monster draws is still a good half of your deck and your access to any given monster in said lineup has not been reduced (Actually, in the case of every hero except Ailus, the case is the opposite), so getting your hands on whichever one you need should usually not be a problem. From there, it's really just a matter of ruthlessly exploiting your Oceans and Stratos to force your opponent into the TCG equivalent of fighting a windmill and keep them in that situation until they break. Pretty much what any build calling itself Little City should be about, really. XD
