Cardians run 6 openers (3x Pine + 3x Flower Stacking), even 9 if you play Light and Dark Skill (with 3x AD Changer which can be swapped into Pine using the skill), yet the starting hand often contains no opener at all. What makes me wonder is why Neos players ALWAYS have Neos Fusion in their starting hand?
About Bamboo OTK, even if you don't open up with Woodland you could still thin your deck very fast. Into The Void is a staple in Bamboo deck. Cursed Bamboo Sword can be equipped to opponent's monster before you use Golden Bamboo Sword to draw more cards. Not to mention pre-nerfed Duel Standby is really a broken skill
