A new arguement in cards’ charms?
I am sure I will come to find out about it in game progress, but it may take something of a long time till I get there:
Anyone knows how Dispossessed Soul in its Battlecry can be controlling a location? That is the prerequisute for its Battlecry to have its effect.
Hey Nuconic, SashaFleyder’s reply is correct - get a location on board and enjoy the Dispossessed Soul’s effect. 
Full list of location cards below:
Paladin: Great Hall - Set a minion’s Attack and Health to 3.
Demon Hunter: Relic Vault - The next Relic you play this turn casts twice.
Warrior: Sanguine Depths - Deal 1 dmg to a minion and give it +2 attack)
Mage : Nightcloak Sanctum - Freeze a minion. Summon 2/2 Volatile Skeleton.
Druid: Hedge Maze - Trigger a friendly minion’s Deathrattle.
Shaman: Muck Pools - Transform a friendly minion into one that costs (1) more.
Priest: Great Hall - Give a minion +2/+1 and draw a card.
Hunter: Castle Kennels - Give a friendly minion +2 Attack. If it’s a Beast, give it Rush.
Rogue: Sinstone Graveyard - Summon a / Stealthed Ghost. (Has +1/+1 for each other card you played this turn!)
Warlock: Vile Library - Give a friendly minion +1/+1 for each Imp you control.
