Kennen
Not to argue too much about the power that Kennen gives the squad whenever appearing anymore, because right in the update 11.5 up to now, the rise of the Dharma guard makes Kennen become more “monster” than ever.

The skill of this unit is also considered as one of the perfect skills when it has the ability to deal great damage and can still stun the enemy for a short time. Especially when in the form of the dharmapala, the amount of armor that Kennen brings to the team is not small, helping the ability of the whole team to exist a lot.
As of the 11.7 update, the guardian is still holding the Meta dominance of the truth, so owning Kennen's sperm almost you have 70% of the victory in your hand.
Sivir
The extremely powerful comeback of the teacher increases Sivir's influence than ever. This unit has the ability to support his teammates and increase his damage with skill, so Sivir is being considered as the main force deserving to be trusted in the middle of the match.

The ability to buff the speed of the dame rear and abundant damage to you to keep your blood extremely good in the middle of the match, especially Sivir Tinh Anh Cuong Giao is an extremely suitable choice if you want to aim for 9 crazy spears, because when you own this unit, the Snowball process will take place quite easily.
