I'm interested to more about how it does against rainbows vs duo decks. I had been thinking about using this Giant frog for this very purpose--as 2 
for 5 base damage is a lurking threat and I'm surprised I don't see more of it in PvP.
Another question: Adrenaline/unstoppable/quint are a lethal combo, but do you end up drawing them proportioned or have to end up wasting cards waiting for the 4th one? Do you think you could get away with only 2 out of 3 of these (i.e., dropping unstoppable or quint) to make the deck run smoother? You'd probably add another frog, another adrenaline and 2 more emerald towers + SoG/druidic staff/phase shield/lobotomizer?
Sometimes I draw them in proportion, but often I have to hold cards until I get all three. I rarely have to discard, though it has happened. I tend to dislike playing an unbuffed unprotected frog because of Otyugh...which, admittedly, Lobotomizer would take care of, and Rain of Fire, since most rainbow decks run them in doubles now.
I can't really drop any of the creature support, because of all the threats in the metagame right now. If you wanted to, you could drop another set of Creature support or maybe two towers for 3 Phase Shield, or 3 Shard of Gratitude, or any of that stuff above.
Against Rainbow decks this deck is pretty effective...it's not so powerful as to be able to win every single game EM, but it loses only 1/5 of the time in my experience. It should do pretty well against Duo decks, except it autoloses to an early Devourer or Speed Poison...oh wait, what doesn't? There aren't that many Duo decks in the t50, though (like I said, it's mostly rainbow), so I don't know for sure.
