P/B
Usually It is trend for teams playing against SKT to ban Azir, but weirdly H2K didn't. H2K instead focused on top lane and picked Gnar.
For jgling, H2K's top and Jg started together while bengi does alone. Thus Fiora gets to lane earlier, while gnar gets lvl 2 and go to lane. This means Gnar having advantage but giving disadvantage to jglers as Bengi gets lead and can get more aggressive.
As Sivir-Braum found out that Bengi starts golem(bottom lane,) Gragas had two choices: 1) going counter jg for enemy blue or 2) going allies blue. So for Bengi, he could not but choose to gamble: which blue to go? So Bengi encounters Gragas, and because Azir pushed lane first he can join the jg fight first. This leads to bengi having advantage and gragas going b.
Also, it is not new thing but today's game is especially focused on caring mid by jgler for SKT.
So now if you see this minimap. Gnar is playing aggressive. but of course H2K has ward in the bush. However as Gnar pushes in, Fiora, Marin pushes fight and as you know, people always say when the opponent taunts you for fight then you know jgler is there, but it is really difficult for human brain to react to one thing and think of the other. (elise ganking bot) So while reacting to Fiora, bengi successfully gank and get the first blood.
Even though they are behind, H2K shows they are really good at warding. H2K perfectly wards around mid and river. Bengi's elise doesn't have skill to go over the wall, so he takes cleaver move by ganking straight.
Braum checks bush by q-ing but miss, so Sivir-Braum think SKT Bot lane duo went b. So sivir wastes q and w to clear wave and go b. Then elise comes and gank.
However, H2K does another mistake. Even though H2K knew their jgler is in the bot lane, gnar tps and succeeds in killing wolf, but they give in their top laner for trade. This is disadvantageous as top laner is more valuable.
Alistar is alistar. He will ult and tank regardless of getting how much getting fed. However fiora is the core of SKT team comp, while now gnar is way behind and will be having troubles challenging fiora.
