I was planning to level up my KRON to level 3 so it would gain Last Stand. But now I think that I will first buy more golden versions of cards I often use. Just recently I leveled up my HUNTER JARX and DEEPLURKER. Now I want to buy golden MERDAALI GUARDIAN, MEDUSA, SEA MONSTER, CAPTAIN'S GHOST, KELYA FRENDUL, OBSIDIAN, MUSHROOM SEER, MYCELIC SLIPSPAWN, THADDIUS BROOD, HAUNTED SPIRIT, REVEALER, PHANTOM SOLDIER, HELHEIM DEMON,SAND WORM, GOBLIN MECH...I know that saving enough HBD for all this will take ages. But this should accomplish two goals: 1. greatly increase value of my collection. 2. To increase the amount of SPS I get for my winnings. I would love to buy some golden legendaries as well but saving for them would take too long.
