I liked the event - it was original, it promoted different decks to be used and it was fun. Just several suggestions - no more RNG lottery reward system, it's bad; more gems as rewards, less useless N/R cards or keys ; WHERE IS TRISTAN?!
Yeah, why is a card like Battle Steer being given out as a reward if no one has any use for it? I get these cards are from the anime but if a reward is objectively useless it defeats the purpose of it being a "reward" at all. I think a good example of how to properly give N/R cards as rewards is the PVP rewards - magical leaf/that new boat monster aren't amazing but interesting & worth picking up
Is nobody going to mention that its not RNG its statistics and if you buy enough lottery thingys you will get all your cards? Like this event was done in the first day, maybe the second if you went chill and after that you still have like tons of time to get the rest and some gems :3 and all keys you will ever need .... probably.
