Hot early collection pro tip: its more credit efficient to level common to uncommon than any other leveling, so try making a deck out of only unupgraded cards

then every match you play (if it makes it to turn six) will get you a new collection level!

and hey, even if the deck seems shitty you might still win. I got some wins with total garbage decks. just need to make sure youve got a playable range of energy costs.
