Here is my attempt at improving Ryuk's beginner guide.
Foreword: Welcome! This guide will attempt to explain you how to expand your deck and become more competitive. Keep in mind I am not very experienced as well, and may not know all the quirks of the game.
Feel free to comment and add on to this guide.
1. Why improve your deck?
2. How to assemble your deck and the advantages of mono-deck and half-decks.
3. Earning the money to buy the actual cards.
4. A quick guide on how to go through your 1st 10-15 levels.
As all of these topics will not fit into 1 post, I will make a post for each section. Please don't post until I have put on all the sections.
Zero's is better if you have that starter, although I think you should extend it more. The end deck is good, but surely it can be improved! This is much better otherwise, it's much more general, and thus less market-dependant. Of course, both guides can be boiled down to "sell your leaders, buy cheap cards, sell cards for profit, repeat steps 2-3"
Anyway you've both been a great help to me - you've successfully convinced me to buy credits!
Great guide. I learned most of these the hard way. You might want to mention that buying a "full deck" (the pack that comes with 8 cards) guarantees you a rare card which an easy way to net several thousand clintz, or a totally awesome card, depnding on your luck.
