Reached Masters and was slotted in at rank 21 on 8/6:
With how aggressive the meta is right now, Vara is just too slow/vulnerable for her cost. So Saber-Tooth Prideleader
takes her spot as your main stabilizing tool against aggro.
Some copies of Xenan Obelisk feel mandatory with a card as fantastic as Street Urchin.
Flex slots you could adjust based on your pocket of the meta:
Nullblades (pressure on unitless, reanimator, aegis)
Ayan (Skycraggro, stonescar aggro, yetis)
Banish (Stonescar mid)
Suffocate (aggro etc)
