I've now saved up enough money for my very first deck upgrade. Which one should I upgrade first: Mark of Elements, Pillars or the monsters? Anyway, this is the deck I'm using.

RoL/Hope can be built with just six upgrades like this:

You can also try -1 Dragon +1 Fractal.
Next step is to upgrade the pillars/pends, and reduce them to 5 each. After that, upgrading lobotomizers is a good idea (though this might leave you with fewer unupped lobotomizers than you want for tourneys). You could also upgrade Dragons for better damage. You can also use Archangels (upgraded Guardian Angels) instead of dragons, as they provide you with faster games (but are weaker to miracle/shields/healing). It's all up to choice really (I personally use 2 Archangels 1 Dragon).
Fractals don't really need upgrading, though upping them helps speed quite a bit. Hope is a debatable upgrade; the extra cost might cost you and extra damage reduction might save you. With the AI giving RoLs top target priority, it might be worth it to get the extra DR. But leaving Hope unupped is fine too.
