First build a regular bridge out of decks than add a bunch of steel in an M shape above it and connect the dots. If that doesn't help than here I found this by searching how do you beat level four of bridgecraft on Google http://www.YouTube.com/watch?v=VbLMzndV9e4 and yes I copied and pasted that! Good luck!
Level 300
Simply craft different recipies until you level up to level 4.
On at least level 50.
an level hundred
You have to beat the elite four and then go to island six and beat team rocket then the cave will be open.
No, because there is no double battle in the elite four
train your pokemon to level 60+ and fight them...
For each gym leader you beat the trick master creates a new level. The last level is after you beat the elite four.
