Good for sustaining below 40 HP.
First of all, if Vander appears as the first augment, consider it for sustain.
Up to level 6, buy Vander and Family champions while adjusting for Janna as it appears, and if Janna doesn’t come out much, spend accordingly while focusing on 3-star Vander and 3-star Family.
At this point, if you hit 3-star Vander, just level up.
It’s important to get 6 Janna and take 3 Family for the bonus.
For Vander's items, initially equip Warmog's Armor, then when you get a Magnet Remover and can get Garen, move it to use Vander as a tank and healing shuttle.
I think Bloodthirster is the best option.
If not, you can give 2 Bloodthirsters for health regeneration, but I found lifesteal to be not great for my playstyle.
Vander needs to be placed on the ends because of the damage dealt by pushing back.
Being Janna, he can function as both tank and deal 10,000 to 20,000 damage, so managing HP well is key when the anomaly appears.
Since he is both D.Tank, maintain health early on and add a high-cost secondary damage dealer to help deal.
I recommend Mel, Viktor, or Jinx.
Many recommend diving during the anomaly, but I usually absorb with the side champion to absorb Garen.
Since there are many situations where I die from low health, feeling secure with health is better so if you have many champions, lifesteal is preferred.
Because it's a sustain deck, the backline needs to be strong to rank first, and I haven't ranked first with this yet, but it's always a sustain deck in play.
It's quite useful but seems underrated, so I'm sharing.
Not an amazing deck, but it’s decent as you accept more Family champions the stronger it gets.
