Really ? Upgrade PILLARS first ? Take a few pillars more and use the deck. 3000
are 2 upgraded cards, but lots of unupgraded cards. Buy some unupgraded cards, try different decks (you can also use the trainer), and if you find a card, that is good enough for you to upgrade, then upgrade it.
Pillars are not the first cards I upgrade. In this deck above, my first choices are Hourglass, Ice Shield , FFQ, and maybe Antimatter.
