For all others who are interested:
I always wondered, if "average cost per turn"-function in the deck builder regards card rarity.
To check it out, I just "bought" a new deck and built it up by:
only common Bricks-cost-cards
only uncommon Recruit-cost-cards
only rare Gems-cost-cards...
of course with approx. same costs (not that easy... average ~10)
Average cost per turn:
B: 5,29 - R: 2,67 - G: 0,6
This also reflects very good, the drawing-chances stated in the help-file:
common: 65%; uncommon: 29%; rare: 6% :-)
Long story made short:
The frequency of card appearance has been thought of. Good work, team ;-)
Hope this helps other players, to me it was very useful, to know that :-)
God, I love this game :-D
Greetz, HivedOne!
P.S.: If anyone is cunning enough, to challenge this new deck, just send me a message! My gargoyles await your soldiers :-)
