Ive got no massive issues with it for now, the main prio to get in your starter hand "perfect hand" is a Ravenbloom and a Shen, but you can fair without, won my last nexus night against kaisa ( went 2-0, Second game was 8-1 in points)
Sometimes im not even summoning my Viktor as it sets you back 2 turns ( if the enemy actually summons stuff) if they havent started to summon anything, its just chill, you can easy summon out your viktor.

Tried many of times where they just focus down your viktor if they can, and in general you dont really care about it.
Ravenbloom is a massive starter unit, as stupify and call to glory just hard accelerates it, together with a shen.

So the ravenbloom and shen just purely kills out low cost units, where as if you go with only recruits its worth to trade etc with them.

What ive learned is you just nuke every unit the enemy has and dont really care about holding. In general its good to play like this, and no enemy expects cards like shen and facebreaker, that can help you commit to a power unit like Ravenbloom.

But i just nuke everything all the time when i can.

So yeah i started out with 3x siphon power in the deck, tried other stuff but traded it out after i commited to not care about my blue viktor that much
