Hey, saw SGs thread today about FG realms and it got me thinking about what else to do to the game. I posted more relevant points in her thread, but didn't want to derail it on the upgrade system changes I had in mind.
i personally enjoy trees more than ropes when it comes to progression. maybe give people options for the upgrade so they can select what they feel would be useful in their deck, with the limit being one upgrade per card. possibilities could already be in the game such as-
increasing atk|hp by +1|+1
increasing atk|hp by +2|+2 and increase the cost of the card by 1
increasing hp by +2
decreasing initial cost of the card by 1
decreasing ability cost by 1 (minimum of 1?)
some cards could do a downgrade type mechanic to make the card cheaper by a bunch and make it atk|hp go down (phoenix, micro abom, etc)
improve the effect of their ability (pandamonium, chaos seed, fallen druid/elf, etc)
a different selection of options could be available for each card to make it less confusing. some people complain they dont have anything to spend their money on (what a nice problem to have?) and i think this could be a two birds with one stone. wow this one ended up much longer than the others, but the talk of revamps got my brain started early today.
SG also mentioned it being a good idea to decrease the cost of upgraded cards to 1000, and i very much agree with her.
