pretty much always win except for bad hand occasions.
One time i was using against an allies deck and they were using halimar excavator to make me put huge amounts of cards from my deck to my grave.
When i had almost 4 cards left i used open the vaults.
Bam! All artifacts and enchantments in my grave, onto the battlefield instantly.

4 x Mycoloth
4 x Vitaspore thallid
1 x wild pare
1 x sprout swarm
1 x fungal bloom
4 x utopia mycon
4 x fungal behemoth
4 x thallid shell dweller
4 x savage thallid
2 x thorn thallid
1 x fungus elemental
2 x psychotrope thallid
4 x sporesower thallid
