Wow and wow indeed That's some serious work was done here, cant slip through unnoticed.
Token of appreciation was sent, please accept this humble bonus code along with thanks.
         I think we have our first legendary spell "left by the elders", vicious and dangerous. (I was avoiding those as they are heavy on gambling element, however this is gambling board after all)
It has a potential for destabilising the entire leader board so it must be expensive in mana in order to make it difficult to cast, only at the rounds end(or close to it) Estimating by current mana gathered by players, it should consume 10-12 mana.  
        I have started a poll for players to vote for the idea. Level 2 spells where suppose to be announced when one of the players casts 10 times but it looks like a lot of waiting so lets change that to 10 times in general (all combined) we have 2 so far. I was hoping you guys would cast puzzle spoofer more often, bedazzling hex(spoofer is not a good name?). This spell will just conjure a puzzle on demand (if I'm AFK for long, no mana will be lost)
        Anyway, fantastic idea, wonder what was the second one
