After noticing the potential of the vetruvian deck i rebooted from last season had, i played it throughly and reached s rank at 54 wins 18 losses. then went on another 5 winning streak and got to #1 at s rank
so, the deck and proof (from start of last season until today)
guide:
Vetruvian more than most factions rellies heavily on position and card prediction. I will try to describe optimal placement of certain cards as well as scenarios in which small advantages can be gained by correct placement.
mulligan:
go for the 2 drops and, in case you arent holding pax or obelyx, keep dune caster.
if playing 1st:
always place your obelysk and pax directly in front of you (so it can move and get the enemy mana spring in case he doesnt grab it on turn 1)
place dunecaster next to top or bottom rune
if playing 2nd:
in case you got no 2 drops, usually it is best to grab your mana spring with a 3 drop and avoid being overwhelmed by an early game big drop from the enemy. exceptions exist, mainly when your 3 drop is an obelysk and the enemy can kill it in the next turn or when the enemy hasnt droped any minions on turn 1. in this case you save your mana spring and put the 3 drop either on top or bottom square adjecent to it or, if obelysk, on top or bottom square adcent to you (thus saving it from lethal).
if you have more than 1 pax/obelysk/dune in your hand, always place obelysk on mana spring and pax directly in front of it. the idea is: in order for the enemy to reach your obelysk, he has to kill your pax, which is a bad move since next turn he has to deal with 2 2/2 minions + obelysk
later game plays:
fireblaze obelysk is very valuable and should not be placed as a regular minion. if you are pushing, put it in reach of as little enemy minions as possible but still close enough to harass, remembering never to place it next or with less then 1 square distance from another silenceable minion (due to lightbender from enemyes or dispels or mankator).
aymara is for the most part a “placed and not silenced = game won” card. specifically against magmar and decks that run silencing minions, its placement is very important: you are aiming to have it place in a corner square of your oponent’s hero with another minion and your own hero next to it, in a “L” shaped placement. so for instance, say enemy hero is in front of you. you want to place aymara right on the top square from where you stand and another minion in front of her, so 2 minions and yourself are flanking the enemy hero.
stars fury should not be held on hand for value. if you can kill 2 minions or summon 3 dervishes with it, generally the right play is to use the card even if you believe it can generate more value later on.
do not question autarch’s gift before trying it out. you can safely predict its rng and use it at the correct time for a lot of value
replaceable cards:
dioltas and nosh are not important, but do fill up the needed roles.
i tried for a while playing allomancers, wind slicers, dominate and rashas curse, but although they may work sporadically, they are not consistent and end up mostly being a dead card in your hand (just like nosh most of the times). if you want to sub them, a third paragon works but there is something as too much removal, so try your luck with nimbus or whatever does it for you 
i will answer specific doubts if you have them
link to my other decks and guides:
Death Knell made a board I couldn’t deal with even though I dominated the curve; with Faie you just sometimes die, that’s life; obviously Vaath could bounce from 2 strength to >13 in a turn, should’ve stepped back instead of hunting his remaining 4 life; Reva started with the strength Spear as T1P1, followed with Ranged and finished the combo T3P1 with Celerity - gg!
