*Checks main thread to see what all the commotion is about*
Oh boy, time to break out the marshmallows. Things are gonna get toasty.
Alright, now time to clear some things up real quick:
First of all, no, I do not plan on allowing Zan's Worldfire spell to literally set the entire world on fire. As was pointed out by Gman, the card's effect in MTG doesn't really translate all that smoothly into an in-game effect here. So again, for the sake of simplicity, we'll simply assume "Exile all permanents. Exile all cards from all hands and graveyards. Each player's life total becomes 1" to mean, "Big fiery wave of doom spreads out over an extensive radius and totally fucks everyone's shit up." Any objections?
As of right now, Zanzetkuken has 3 unused units of many (all red). The mana accumulation mechanic in it's latest form (like most the mechanics in the game, it's subject to change as I come up with adjustments that I feel will improve its overall balance/efficiency.) works like this:
At a Badassery Level of Average, pooling together a single unit of mana takes 30 minutes. For each level above average, this time is reduced by 5 minutes. For every level below, 5 minutes is added. The time can be reduced a further 5 minutes if Zanzetkuken is in a landscape associated with the type of mana he is trying to collect (for any who don't already know: Mountains=red, Islands=blue, plains=white, forest/jungle=green, swamps=black), or increased by 5-10 minutes if he is in a landscape that is at odds with it.
With his current Badassery Level of High, Zanzetkuken will, without any land modifiers, be capable of pooling together mana at a steady rate of 1 unit every 20 minutes.
