deepdown, this is heavy evidence supporting the claim that Fire Nymph (and possibly even Rage Potion) is a desync trigger. I think Zanz needs to know about this.
For those that don't know, desync is not a random thing. It is a specific event that is triggered by different data being sent to both players from the same function. There used to be a TON of triggers, which is why PvP was both unpopular and infested by desync issues. Most of those have been fixed, but with the inclusion of new cards and strategies, new triggers have started to surface. This may be one of them.
