Blastoise is one of the few bulky Fake Out users, other than Scrafty. The difference in between Scrafty and Blastoise is that Blastoise has the ability to burn physical attacking threats with Scald, and tank them. Fake Out is needed, as that is the only reason to use it over other Scald users, such as Milotic who has more bulk and Special Attack. Ice Beam provides coverage against Dragon and Grass types, which Scald doesn't hit. Protect is needed for predictions and burn stalling.
The item allows Blastoise to easily survive Electric attacks from things like Zapdos and Eelektross. The ability choice only matters if running a Rain team, but other Rain Fake Out users like Toxicroak and Ludicolo generally are better. 196 Speed EVs allows Blastoise to out speed neutral natured, max speed Hitmontop by one speed point. The rest are put into HP and Special Defense, and physical attacks Blastoise can easily shrug off.
