Akshan is a dominant lane bully who punishes melee champions with constant procs and range. You lose almost every trade before level 3 and must play for your level 6 power spike. Post-6, you have the tools to shut him down if you manage your HP and energy correctly.
Amumu Mid is a niche pick that relies on high base damage and locking you down for his jungler. You have the mobility advantage, but his passive makes you deal significantly less damage with your and autos. It is a war of attrition where you must bait his CC to win.
This is a high-mobility skill matchup where spacing is everything. Aurora wants to poke you down and kite with her superior range, while you want to find an opening to stick to her and burst her before she can jump away.
This is a survival-until-six matchup. Jayce is a lane bully who wants to poke you with his range and then jump in for a kill with his hammer. You win by managing your health early and exploiting his lack of a combat ultimate once you reach level 6.
