This card is present in oEtG so I've been playing around with it a bit. The most amusing combo so far is with nymphs tears and quantum pillars.
The combo with EQ and PA is also pretty ugly if pulled off right.
When used with buffs or CC its unpredictable enough that it at least makes building decks around it tricky.
I had some limited success using it with quint+sow+mirror shield. Hard to get consistent results, but watching the opponent fry themselves with their own creatures is hilarious.
It certainly adds an exciting element of chaos and mayhem to the game.
