Yesterday I was playing my mage deck, versus another mage deck. I had the mana wyrm out. He had a secret out that I was pretty sure was counterspell. I played my least valuable spell, and the counterspell secret sure enough popped out and countered it.
My mana wyrm did NOT trigger on this played spell, presumably because it was countered.
The very next game, an opponent played Gadgetzan Auctioneer. I damaged him, but couldn't kill him that round, but I had a counterspell. The opponent played a spell. He drew a card, and then the spell was countered.
What the fuck?
How do these triggers work?
Theories:
1- Each card has a different inbuilt priority. For instance, Auctioneer is super broken and some dev wuvs him too much, so he's top priority, and Mana Wyrm is lower, and Counterspell is somewhere in the middle. If this was the case, we would expect a deck with Illidan, Mana Wyrm, Auctioneer, and Questing Adventurer to always have their effects triggered in the same order.
2- Each card has a priority based on when it was played. If this was the case, maybe the order of play of the counterspell versus the mana wyrm and auctioneer mattered.
Any ideas?
