Have you considerd Increasing Savagery? I made a similar deck, deck:increasing-unblockable and having permanent buffs on your deck:invisible-stalkers is great.

This looks like a straight up aggro deck with light control elements. I'm not sure what you mean by its versatility other than the sideboard options. That is fine- I have no problem with the deck list, I'm just not sure what you mean when you say 'versatile.'
I think if you want to take advantage of the pike you need less creatures and more spells. All of your creature choices are great- just run fewer. I would personally run less Cryptoplasm and Mayor- they don't have evasion. Increasing Savagery would be excellent in this deck. Hunger of the Howlpack and Travel Preparations would go in that same direction.
Evasion turns combat into a modal style- instead of your creatures vs. their creatures, it's a footrace between you and your opponent. I think you should run a boatload of bounce- Unsummon, Vapor Snag, and Disperse- so that while you're consistently hitting with Stalker or flipped Delver, you're also disrupting your opponent's game plan. Hope this helps!
