Wow, thanks for the tips & guide, I could not understand most of the jargon 
I might look into MTG Online too if I could not visit LGS frequently, just that I am very reluctant to spend more $$$ to get digital magic cards.
Yes I have heard about the Singapore GP, as told by the LGS boss which I visited that day, the registration fee is kinda steep though and most importantly I am not around on 15th December, will only be back to Singapore on 16th December, most likely. So probably would drop by on 16 or 17 to look see look see.
