Mongskin Parka

Equipped creature has +0/+1
{2}{g}{g}: Equipped creature gets +2/+1 until
end of turn.
{g}: Equipped creature loses all colors and becomes green until end of turn.
The mongs are known for their numbers. too many
mongs is bad for the enfironment, because when the
mongs die they release their mantra energy back into the
ecosystem. The mong numbers can't be too large, unless
it is time for a slime year.
