I think Metagross will win alot. Sorry if it's getting old, my metagross fanatic-ness, but its just such a good card. Mixing various Psy and Metal types is so strategic. Its so versatile. Exeggutor is good with it... I managed to make the SS steelix work wonders last weekend (7-0 record at league with it) And well it was just amazing.
I'm not so sure Monarchy and Beedrill will do well. Monarchy depends on having ALOT out to be exceptional, and so does beedrill. The energy costs are fine for both decks, thats what makes them good. And poison effects and getting others out, but Fire and Psychic will eat these decks apart.
