PROMPT #1:

 First of all, Sir Devoir better hope that he can still speak English if he gets reincarnated. As a Pokemon, he had to learn English because all he could say was the name of his own species. However, if Devoir had to introduce the concept of hockey to a new world, he would start by taking an opening between two trees, a few sticks, and a round stone and challenging people to try to get the stone by him by using the stock to push the stone. The first time on dirt would be a bit rough since it would be hard to move the stone, so he would move to concrete and nets made out of stcks and rope.

 He would eventually start getting other goalies once it starts to catch on, and uses modified football and skateboarding equipment to simulate the hockey gear. It would take a very long time before it would become any kind of sport, but it is a good start. He wouldn't change any rules from the old hockey he knew, and would even serve as a ref for a few games.
