Hi, the gem reward is not given to all players but some of the players, that means some players will get it and some will not. For 3000 gems only 30 players will get it, 1000 for 100 players, 300 gems for 500 players and 100 gems for 100 players :)
Last year's champion really deserved his title if you watched his brilliant gameplay. But still, in the tournament where everyone plays almost the exact same meta cards, coin-flip luck matters more than skill
I like the tournament rules. Hope there will be similar events in the game.
Oh wait, we even have more than 3 Japanese to select from
Rules for WCS 2018 Finals
♦ About the Deck:
5 Decks, each set to a different Legendary Duelist with a different Skill.Duelist can only have 3 copies of the same card across their 5 Decks.In addition, they can only have 1 copy of a Limited card and 2 copies of a Semi-Limited card across their Decks.
Side deck is an important part only in TCG. Till date, DL never had any tournament which require you to play with a side deck.
WCS 5 decks rule is very interesting. You will not know what is your opponent's deck order. You can always start with 2 of your weakest deck and lost. Then save your 3 strongest deck to win the remaining duels. Japanese are good in mind reading.
We never had side deck in an official tournament or any event/game mode. So it is a NO until Komoney decides to implement it. The Japanese was organizing tournaments based on WCS rules and Dkayed never. No surpise if he lose in the first round.
