Great art!
As for the active skill: is it for any spell cast after the skill is activated? By either side?
Also, if I activate the skill in turn n, and then I cast a spell in turn n+5 for example, is it still consumed?
It affects both sides (i.e. it will eat your next spell if you cast one after activating, otherwise it will eat your opponent's next spell if they cast one next instead).
And yes, once activated, the mantis simply waits for the next spell that gets cast, no matter who casts it and no matter how long it has to wait.
What about Relic & Null Mantis infinite buff combo? 8)
I figured that would be an automatic exception... Even so, its not really an infinite buff. The mantis' ability only absorbs 1 spell per activate, so at best you are paying 2
+ 1
for +1|+1. Thats pretty inefficient.
+2 cost for +4/+4? Dang
I like how it can be used to nullify the opponent"s spells
Hmm... Remember that upgrade typically counts for +1 effective cost as well...still, I may have over done it a bit
I guess +3|+3 would be better...
