This is a reminder that you can/should complete the survey. They did improve some minor things this time, so it's actually possible that they fix some other things for the next Duel Carnival.
Just make sure that you formulate your criticism in an OBJECTIVE and REASONABLE way!
And if you liked the event the way it was, you can complete the survey as well...
One thing I really want them to implement: make it so that you have to play a deck that represent by the side you choose.
Like, if you're in Spellcaster side, your deck have to contain at least 6 different Spellcasters.
If you're in Giganticastle side, you have to play a deck that includes a minimum of 5 Rock-Types and 3 Tuners.
