Well before you go buying tins and stuff and rabdom cards, you need to know what you want to play first, this helps make spending alot easier. Put the deck together first, we (the community) tell you want to put in and you go and obtain those cards. Be sure to download redshard to help playtest the deck before you go and buy stuff for it.
If you're going to post a complete 60 card then post it the deck garage (you'll get more help there).
So of the better tins out there are:
Garchomp C lvX tin
That's pretty much the BEST tin to get right now and Garchomp C lvX is a very good card.
