As a very smart and sober twitch streamer (Judge, https://www.twitch.tv/judge) once told his chat, "it's important to establish what your role is in each game. Are you the aggro or the control?" In a spiteful deck like this, which also has the capability to go late game, I feel this is a very important question to keep in mind while playing. Against decks like big priest or tickatus warlock, your chances of winning late are probably not very high. In these cases you are the aggro, so you need to end the game as quickly as possible (meaning not getting full shudderwock value). Obviously, against aggro decks, you are the control and just need to do anything to survive, while your opponent is trying to end the game as quickly as possible. Against most tier 1 decks, this is how most of the games will play out, unfortunately. Of course, this is supposed to be a  meme deck, and the goal is to face either a really bad opponent, someone with an even worse/slower deck than this, or face a priest who runs 30 board wipes and no other cards, so you can generate infinite shudderwocks and throw a bunch of eyeballs at the opponent.

We of course know historically that Prince Keleseth is very good in spiteful decks because you run a lot of minions for him to buff. In this deck he gets extra value with cards like Brann Bronzebeard, Zola the Gorgon, Shudderwock, and Barista Lynchen (although generally it's correct to just play him on turn 2 or as soon as possible). He also has a handful of good targets such as faceless lurker, Carnival Clown, Saronite Chain Gang, and c'thun if you are bouncing keleseth a lot. 

There are a few uncommon cards in this deck such as Faceless Lurker, Twilight Drake, and Omega Defender. These cards are good for making a big shudderwock board, and if they trigger before the clown battlecry then you will make a pretty beefy board. The omega defender buff also isn't particularly bad if you played C'Thun before shudderwock. 

Eye of the storm can be used to corrupt the clowns, but you really don't need to corrupt them. Playing them uncorrupted will increase the odds that you get to duplicate some of your buffs when you play Shudderwock and get value off of Spiteful Summoner.
