Great thanks guys. That was how I thought things worked but my wife is convinced I was cheating.

I don't really think 4ele+nature will need the massive 3x for all other spell cost. mainly because there is currently very little synergy with the elements and nature. for example all elemental cost creatures are non living so they can't use any nature spell abilities. as it is that mage will use nature creatures with nature buffs and just have access to your choice of attack spell element.

 I would guess that all ele cost creatures are non living (unless they have multi cost like lof)

 so this mage can be treated like a stronger wizard (nature is stronger then arcane) so it will need 1 kind if 3x cost but not all other. perhaps dark or war

True, I guess I was just thinking thematically as a geomancer type mage if he was forced to use only elemental type spells it would be unique.

I've been playing this for only a few days, but I'd love to see more creatures. Something I'd like is elemental Golemns. You could summon a giant Ice Golem that would have high attack, high health but would take 3 dmg every upkeep phase as it's melting.  Or a mud Golem that has decent stats but each round gets a defense token added to it, max of 3 or 4) as it's hardening after being summoned. Once it hits the max it gets the slow trait.  I think things like this could add more strategy to the game. Do you blitz the mud golem before it can reach it's strength, is the ice golem worth it if you don't have the healing ability to keep it up? There are other things you could do with this kind of mechanic that I think could be really fun.
