Unfair Play in Champions

Someone please explain how I was unable to use affliction or poison and lost this game. This is exactly why I believe this game favors players. There is something going on behind the scenes that has given players better odds or algorithms. I see things like this in matches often in my years of playing Splinterlands and the only answer I can come up with is that the game favors players. There is absolutely no way that this game should have gone down the way it did. I can handle losing, but losing like this is ridiculous and not fair at all. Does anyone else ever see this kind of play go on in their matches?

I would love to hear from you either way, but please watch this and tell me I am wrong. Thank you for your time.
