The wrath of CORN

As my grandfather used to deny, today is not a good day to die
Here is a surefire strategy for you, noone defeats the yellow pikachu
Go CORN early and go CORN often, if you can't, get the stones you know you want them
No other tactic is its equal, soon you'll be master of Peurto Rico
If not at least you'll have some CORN

PS Why CORN and not corn? ask my left budgie I'm dissinterested
