Boo, PT card...anyways, today's CotD is Octillery from the mentioned set. Statwise, 90 HP is average for a Stage 1, +20 Weakness to :lightning is ok for now since :lightning decks aren't much around, no Resistance, and a bit expensive :colorless:colorless to Retreat. Water Vein I think actually has a bit of potential; you reveal the top 5 cards, and for whatever ones are Energy, you deal 50x for each heads you flip, meaning you can hit up to 250 damage maximum (not likely, but still...), all for no Energy. And the best part is, the Energy (and other cards) get shuffled back into your deck instead of discarded, meaning you aren't losing anything. Combo'ed with something like Delcatty from PT, this could be a nice way to deal an (almost) consistent 100 damage every turn, all for zero Energy. Octazooka is ok, dealing 40 for :water::water: and has the chance to completely shut down your opponent's opportunity to attack. But still, Water Vein is better.
Modified - 7/10 (Flippy, but has potential if anyone can figure out how to run it properly. Even if you wiff just 1 Energy with Heads, Water Vein is a very cost-effective attack. Great fun deck if anything)
Limited - 9/10 (Since you're playing a higher than usual number of Energy, if you can get Octillery out, you can do some serious damage)
Unlimited - 1/10 (Not much use here)
