You can Ritual Summon this card with "Primal Cry". Once per turn: You can reveal 1 monster in your hand, then target 1 face-up monster on the field; this turn, that target's Level becomes the revealed monster's. Once per turn, if another monster(s) in your hand or field is Tributed (except during the Damage Step): You can target 1 monster in your Graveyard; add it to your hand.
Can retrieve monster from the grave.
First effect is not very useful on it's own.
Can only retrieve monsters after you tribute for something.
Use the effect of Vennu and reveal Possessed Dark Soul in your hand to turn a monster your opponent controls into level 3, then summon Possessed Dark Soul and tribute him to take all level 3 or lower monsters your opponent controls. After that you can use Vennu to retrieve Possessed Dark Soul.

the drop rates were so low i only managed to get one... oh well. i managed to steal a blue eyes using this and possessed dark soul lolol
Archfiend Vennu deck. Hard to run and very impractical but still a lot of fun. Basically use level1-4 Archfiend card (Trance Archfiend) and change it to the desired level using Vennu to combo with Archfiend Palabarynth. This method allows you to summon any Archfiend card you want. After you can use return from the dark dimension or Trance Archfiend effect to bring back the banished card/cards used to summon said Archfiend cards.
Activate its effect by revealing possesed dark soul in your hand. Target an opponent's monster to make it level 3. Then normal summon possesed dark soul, use its effect to take control that monster. Now Vennu's effect can be activated too.
