I think scratchcards are a good way to get your mp up quickly. I buy the cheapest cards (x marks the spot) but occasionally I buy the Shiver Me Timbers scratchcards because it tends to be every 3 cards you use you won't win. (so the first 2 you will win but on the 3rd you will lose)

I'll leave this here for anyone who's interested anyway~
