Which one

[slovenc555]

Ok, so I went selling all the non-rare cards I got from spins and I got 3472 € out of that. so, in a mono fire, which card should upgrade (besides fharenheit and the dragons)

When in doubt, upgrading pillars is useful (if boring).

I'll say
Ash Eater --> Brimstone Eater - you generate one fire quantum per turn, plus you do a little damage which can be critical to finishing a game
Burning Pillar --> Burning Tower - You get one quantum for playing it
The rest is pretty much a use faster and earlier

These upgrades allow for new strategies:
Upgrading the Phoenix and Immolation allows you to play a Fractal Phoenix deck.
Upgraded Ash Eater provides Fire quantum along with their 2 attack helping to compensate vs. Earthquakes.


The other upgrades basically just makes things cheaper and/or stronger.  However, both Rain of Fire and Lava Golem are usually upgraded in a False God deck.

Thanks guys. I already upgraded the asheaters, but I gathered another 1500 since than (yeah, wasn't playing much these days)
