If you guys haven't seen my "Second Upgrade" topic, well, I suggest that there should be a cheaper first upgrade, and then a ridiculous upgrade like 10k for those higher league people... But people disagreed, and we are thinking,
1k for pillars
1.25k for bazar cards
1.5k for rare cards
and then theres the
Upgrade A (now) for the horned frog,
+2 attack, giving
x
, 5/3.
make another one, alternative, that costs 750 and gives half the bonus... On a different stat
Horned Frog B +1 HP, giving
x
, 3/4.
Then there's the Horned Frog A+B, giving
x
, 5/4.
