yesterday I Islanded an opponent's Possession while possessing him and then spent all his coin tokens.
Now that's cool. Meet Island: disastrous card-stealing attack!
Even worse if you used his BoM as an Island to remove his Possession.
And even worse is when you.... I got nothing.
And even worse is when you use his BoM as an Island to remove his possession, then another BoM as an Ambassador to return 2 provinces, then another one as a Masquerade to pass you another one.
