I just got a southern island set and the cards are so useful, and have
lots of possible combos.  One is putting the tentacruel in a raindance
deck.  SI tentacruel's fist attack reads:
W  TENTACLE GRIP- Flip a number of coins equal to the number of W Energy
attached to Tentacruel.  For each heads, draw 2 cards.
This attack can replace all card drawing cards in raindance.  Just load
energy on him, use that attack and use energy flow to get the enrgy back
on your next turn, after retreating.  His second attack isn't bad
either.  For 2 water he can do 20 with a chance to paralyze.
