Yea, bored, FG's have fully upped decks. They only need 4, which is about how much one gets in the beginning (well, 2 or 3, but they get 4 in like 2-3 turns) and in 2-3 turns of the peace that you have, you can deal 20-ish damage, they can deal 50-ish damage, you have 50, they have 180, so that becomes 130 damage giving you 26 poison...
As far as the 2nd grader being able to do this math, I learnt division in 4th grade, caught on, and is now one of the smartest math students in my Middle School (But I'm an 8th grader so that doesn't really count...). But the curriculum goes as division (at least in my head) is learnt in 4th grade.
