I am hoping to get one of the presale packs but may not get enough vouchers to do so. I will start looking at my current deck to see which splinter is the strongest. I have already leveled up a few of the new reward cards to level 2 so may want to look at those splinters summoners to consider starting with. Thanks again

If I may give you an advice, I think it's a good idea to actually not invest in packs during the presale. You may overpay these 5 cards greatly. A good idea is to wait until the packs are added to the game (this may take some time). Then you can buy the cards from the market that you need most (like summoners). You can even sell your vouches to earn some funds to later invest in cards.

This sounds like a great idea. The only reason I would purchase a pack is for the chance to get one of the promotional cards. Even with the chance for purchasing one pack is only 2%, If I was lucky that card would be worth a lot I figure.
