"What's a Galio" goes the old reddit meme. Galio is an older champion, but one who still has niche uses today. He's unique in the fact that he can build MR and gains AP from it, and he has an AOE taunt Ultimate that can utterly annihilate a team. His damage and shields aren't anything to scoff at, and against many AP midlaners. laning against Galio can be frustrating and even dangerous given how easy he is to gank for after six.
Passive – Runic Skin

Q – Resolute Smite
Resolute Smite: Galio fires a concussive blast from his eyes, slowing and dealing damage to enemies caught near the impact point.

R – Idol of Durand
Galio assumes the form of a statue, taunting nearby enemies and storing concussive energy as they attack him. Galio then bursts from his statue shell, releasing the stored energy to damage surrounding foes.
Galio channels for 2 seconds, taunting nearby foes and blocking 50% of incoming damage.After channeling, Galio deals magic damage to surrounding enemies, plus an additional 10% damage for each attack he suffered while channeling.
Not playing a champion that does primarily magic damage goes a long way. Galio is a relic from a time when League still had harsher punishment for incorrect champion picks, so he still abides by many of those rules, this means he also has a harder time against champions that he wasn't made to counter.
Playing a champion with a delayed disable is a good idea against Galio. If he ults a Volibear for example with Rolling Thunder active, it'll interrupt his ultimate, which is basically most of what he offers his team.
Galio's mana costs are unforgiving. Usually if you just sustain through the lane, you'll leave him a bad position in which you can pressure him. This is even better for you if you're using a manaless champion.
She has her own shield and a lot of damage that, while it comes out in bursts, is available often enough for her to abuse Galio. She also has her own form of hard CC and no mana gating to make her question whether or not she actually has the resources to kill Galio.
Much like Riven he does a lot of damage really fast, and has his own built in hard CC. Even if Galio tries to run and hide under his tower, Pantheon has the ability to very quickly effect other lanes, punishing him for being passive.
Is this 2012? Fiddlesticks can cancel Galio's ultimate with two different abilites with fear or his crow. He also has really good sidelane ganks, if for some reason he's ever given the opportunity to roam, however these two should never kill each other without jungle assistance.
You should always be building Magic Resistance. Banshees Veil is good, do NOT build Mercury Treads unless he's the biggest threat on the team as they do not decrease the length of his taunt. A QSS has a lot of value since it denies him the CC that goes with his ultimate as well.
