Don't get me wrong, I like the idea, but if a certain champion has a skill-advantage over another champion =/= countering. Sivir would counter anyone with skillshots and projectiles, but that doesn't mean that she'll be dominating her lane against those champions.

For instance, saying that Sivir counters Blitzcrank because of Spell Shield is, bluntly put, false, because a good Blitzcrank is able to trick Sivir into using Spell Shield, without actually using Rocket Grab, having Sivir waste her Mana. Hence, with some experience, you'll be able to counter Sivir with Blitzcrank.

Also, saying that Cho, Vayne and Olaf counter Alistar's Unbreakable Will because of their ability to deal true damage, is false, because Alistar's Unbreakable Will = increased armor and magic resistance, hence Cho, Vayne and Olaf would counter everyone.
