Glad I could help :). Yeah it's not just your area, emmersblade is hard to get period :(. You can use 3 on kc though. Since you only have the 1...I guess keep rat. That's what my friend used before he got the 2nd emmersblade, but he finally broke down and bought it bc of how much better it is. Of all the cards I said to use, he would be the best option to buy.It realy does help more than you would expect. Curse it for being so expensive :(. Only 2 is "needed" for the engine though so 3 isn't absolutely necessary....Just more helpful :). And instead of the 3rd emmersblade use a 2nd airbellum or sangan (or keep hamster). Sangan makes up a little for not having many emmersblade and airbellum is pro. That discard effect is really annoying haha. If you can only get 1 pod, keep reinforcement. You need it for the search power, particularly bc you have only 1 emmersblade. No, 2 pod doesn't really hurt you (3 is overkill though). But sabers don't really even need pod (tht'a kinda why I like them). I wouldn't worry about getting another irl, go for emmersblade instead if you can. Super-nimble isn't crap really...it's just not as good as other cards IMO. You're searching the searcher basically haha. Maybe keep it bc of the lack of emmersblade but just try it without him, I doubt you'll miss him. 2nd mst doesn't matter much, it's just worked better for me. Just keep the 2nd trap stun if you only want 1. 3rd book isn't for sure needed either, but saber decks leave a bit of space for tech and book is pretty amazing this format. Poa...eh. I like this card but you usually want monsters in the grave to bring it back with your numerous revival cards.
The synchro choices are all about options. With wurm you have an excess of options. You can synch for 9s easy, but rarely ever twice, much less 3 times (and gottoms>wurm). Urbellum kinda sucks. Only reason he's there is bc of boggart. Sometimes you will be stuck with only him and a level 3 tuner. Also urbellum is a saber so yeah. Android is optional since you have Beast. Only occasionally is it nice to have him like if you duel bw where catastor isn't much help. I don't care really if you don't add him
