Runeterra Deck: Control Viego Patch 3.7.0

I exclusively played this deck from Gold 4 to Plat 4.
This Deck has multiple win conditions.
If you're against aggro, use crawling viperwyrms to get beneficial trades against 1/1's.
Everglade collector and Camavoran dragon are there to heal up or deal instant damage to the enemy Nexus.
In control matchups you just want to evolve your Viego asap. You can also apply early pressure and finish them off with a surprise 'Atrocity'.
'The harrowing' is really good for healing in combination with 'everglade collector' or just to instantly evolve Viego.

Weaknesses: Xerath decks / Early game challenger decks.

When Xerath is lv3, your deaths become obliterates. This makes your deck significantly worse and you should always try to get rid of Xerath over anything else.
When you're against aggro/challenger, hard mulligan your hand for your 1 and 2 drops.

Strenghts: Other Viego decks, Yasuo, Leona, Trundle, Tryndamere.

Go hard early, get in as much chip damage as you can and finish them off with drains and Atrocity.
In the Viego mirror, you're stronger early game, try making setups that are hard for your opponent to play Viego into.

Good luck!
