I was playing against Chaos Lord and he stole my Sanctuary. This allowed my creatures to get past his shield (since his quanta pool could no longer be affected during my turn), but for some reason, my Lobo (Elec, really) was still blocked. Strange thing is that it didn't take anything out of his quanta pool, but his HP was still unaffected.
I recreated this bug in the trainer with the following decks:

I waited for his Sanctuary and Dis Shields to be played, then played my Lobo. Bug was reproduced, as I did 0 damage and his quanta pool was unaffected.
Before I ended my turn, AI has 100hp.
My attack is absorbed. He is still at 100hp.
Thanks!
