Rhombus - read the TFL blog.

But basically, during the first 24 hours of this event, there was a deck matching bug. You'd always get matched with ridiculously weak decks (R1/2/3 decks). So even T2/3 decks could hit streaks of 300+ easily if you tapped fast enough - this earned you mad points and chronogon. So those who played a decent amount in the first 20 hours of this event milked the bug for all it was worth and got 9 mirages easily. Sorry to those who came late to the party, but that's life (and mobage), I guess.

My estimate is maybe 100+ T2ers took advantage of this to upgrade their decks into pure Mirage decks. To these newly-minted R5 decks - congratulations! You should try and use your increased firepower to try and ally up with T1 players, who might be happy to have another reliable heavy hitter on their list (i know i would)

The other 100+ all-mirage decks running around belong to T1 players whose R5 decks would've been pretty deadly even without the Mirage bugs anyway so the Mobage error didn't profit them too much.

A lot of players obsess about the game strategy - whether attack is better than defence, what's the best matching weapons for this or that bot, etcetcetc. They forget what's more important is metagame strategy.
