Shadowverse

This is one of those decks where I doubted its effectiveness. On paper, everything looks good and logical, but in practice, it's quite weak. It doesn't have a single summoner, which is a failure for a Knight. In another deck, I have a lot of summoners, and overall, the cards are better, making it easier to play. I even managed to defeat a Dragon with Bahamut quite unexpectedly on my last turn.
I also saw a Knight deck focused on ambush, which proved to be very effective, but for some reason, the opponent didn't finish me off and forfeited.
