Senna

Senna is a range that can easily destroy your boxes. Senna often leaves glacial augment for the slow which combines with his passive. Senna is very strong in support and also in adc it's a very difficult matchup because if she takes a red trinket she can destroy all your boxes.She is Shaco's biggest counter during the laning phase.

Lux

She can hit a cage and 1 shot you before you do anything. The laning phase is hard with her E, she has a shield and a range for counter you're box. She has a huge scale, you can't outscake her. I recommand you to ban her.

Yuumi

The worst support ever, stay on adc for heal in laning phase you can't poke her or kill his adc because she can heal every time. When she scale the heal is so huge.

Pyke

You can counter his grab or stun but be careful when he has his ultimate because he deals true damage and if he hit you you're dead. It's a melee champ in laning phase you can poke him.

Leona

She is tanky but it's a melee champ, you just poke him with you're box and dodge the grab. Becarefull she has a good CC. You can't really kill her before you have the liandry but if she make a mistake punish her because she has no escape.

Bard

Bard is a good roamer, you can follow his roam because you a have a good kit for this. In laning phase it was really difficult to kill him if it's a good player because he can place a heal and let adc farm solo and roam.

Lulu

She has a big shield, she can press R for save the ADC. She shield of Lulu is very OP and Shaco can't counter this and it's not easy to poke her or his adc.

Sett

It's a melee champ he has no dash even if he play hextech flash. You can poke him a'd kill him easily in laning phase. He can stun you're box just becarefull of this.

Rakan

Rakan is a support which has a very good engage.

Morgana

Morgana is a pretty easy matchup because she mostly has a spell that you have to dodge her Q, you can dodge it easily with a box or your Q or all just by dodging it. Its BalckShield prevents your boxes from fear of the person being protected by this blackshield. The more the game progresses, the more useful you will be compared to a morgana cage, especially since it is rather easy to dodge if you are careful.
