If you are a strategic player who prefers simple yet effective champions instead of complicated ones, then this is the list of champions that suits you:
Kassadin – Mid Lane

In the laning phase, Kassadin can heal significantly with the rune Fleet Footwork, farm, and poke enemies continuously with Null Sphere (Q) + Force Pulse (E). However, Kassadin’s laning phase will be easier against magic damage champions rather than physical damage ones.
In the later stages, Kassadin will become a true assassin with a skillset that deals massive damage. Notably, Kassadin’s skills are extremely easy to use and land, making it nearly impossible for enemies to dodge and outplay him.

Ashe – AD Carry

In the laning phase, Ashe will try to farm and poke enemies with Volley (W). Since she lacks escape skills, Ashe can scout enemy jungle with Hawkshot (E) and stay close to her support to ensure safety while laning.
In the later stages, Ashe can deal tremendous sustained damage with Ranger’s Focus (Q), allowing her to take down major objectives or engage in team fights easily. In team fights, Enchanted Crystal Arrow (R) helps Ashe initiate combat or safely protect herself from enemies trying to take her down.

Miss Fortune – AD Carry

In the laning phase, Miss Fortune (MF) can poke and farm with Double Up (Q) and Make It Rain (E). Due to her passive Love Tap allowing MF to deal significant damage on the first attack, she can take advantage of this to push minions or trade spells with enemies.
In team fights, the key for MF is choosing the right angle to unleash Bullet Time (R), sometimes wiping out the entire enemy team with that ultimate.

Nami – Support

When laning, Nami can heal and poke enemies with the same W skill, making it extremely advantageous. Her ability to knock up with Aqua Prison (Q) is also enhanced with enemies being slowed by Tidecaller’s Blessing (E). Like any other support, when her AD Carry is targeted, Nami should knock up the opposing AD Carry and counterattack with her powerful healing ability.
In team fights, Nami will fully utilize the potential of W, furthermore, the combination of R+Q will control a large part of the enemy team, giving her allies space to deal damage.

Taric – Support

When laning, Taric can hold the lane with his durability and healing from Starlight’s Touch (Q). During ganks, Taric can buff the combo of W+E to easily stun enemies. Since most junglers have engage skills, this combo from Taric is very easy to land.
In team fights, Taric’s wide-area stun capability will be a deadly weapon in the eyes of enemies. Meanwhile, his ultimate, Cosmic Radiance, granting allies invulnerability for 2.5 seconds, will help the entire team pull off unexpected comebacks.
