Any deck that you play with is a deep, well developed, and laser focused deck that requires skill and finesse to play.
Any deck your opponent plays is a no-skill, broken, clown party that a toddler could pilot to victory.
If you win, it was due to both your play skill and your deck building prowess.
If you lose, then it was due to good luck and cheese on your opponent's part. And terrible luck for you.
