Since there is no suggestion area, or if there is, I completely missed it, I will put this here, as it is directed at PvP events.
To prevent the use of the same old decks that you see in all events and tourneys, the ones that 99% of the time will be used by a lot of people, like mono aether, destroyer rush, some sort of graboid deck, speedbow. All of these are 30 card decks, and my suggestion is simple. If anyone comes up with a new pvp event that is accepted, and any pvp event coming up in the near future, put a 40 card minimum deck size rule in effect. This will help somewhat with being rushed with the same lame decks. Mono aether wont be able to chain dim shields as well for example, or you might not draw that needed cremation in the destroyer rush. Might mean people will use more stalls, but I would rather play a longer, more eventful game with lots of counters rather than a 4-6 turn game because I was rushed.
