With multiple spamming pokemon powers available via evolution, this is one deck that Phione would actually significantly benefit. Drop the tropius and celebi, and add 3 phione. Leave it active until it's KO'ed, then use a scramble'd venusaur. You might wish to drop the dawn stadium for a 1-1 sceptile (1-1-1 if you run phione). That 2 or 3 cards essentially doubles your energy supply. Castaway without tools isn't as good as straight draw. Go steven's advice.
