Alrighty.
Here are some tips:
If the card has poor power (only one Toribash logos) you can have 3 duplicates of those in your deck.
If the card has moderate power (two Toribash logos) you can have 2 duplicates of those in your deck.
If the card has superb power (three Toribash logos) you can only have one duplicate of that card.
This rule while building deck, together with the upkeep rule is the very important rule!
Also, unless your luck is not 6 points, your deck always has to have 1 DQ bad luck card.
If you decide to use Blue Belt edition together with Noob Pack edition and your Luck is <= 3 points you also must have 1 Missclick Bad luck card in your deck.
You can combine Noob Pack and Bule Belt pack cards to form your deck (best option since you have lucky cards in the Blue Belt edition and they can help with those bad luck cards)
You have 15 points that you have to assign to STRENGTH, SPEED, SKILL and LUCK.
Maximum amount of points that you can assign to any of these characteristics is 6!
Good luck.
