I'm not sure how this works. When someone played it against me, they said the effect meant I couldn't play more than 1 non-artifact spell a turn.
Is this true? Does this card really stop your opponent from playing more than 1 non-artifact spell per turn?
I tried to make sense of it myself, but the wording is 'fuzzy' to me.
Each player who has played a nonartifact spell this turn can't play additional nonartifact spells.
What confuses me is the 'this turn' in the ability. It leads me to believe the effect is only active during the turn it is summoned.
The person I was playing against believes the effect persists beyond the turn in which it is summoned -lasting as long as it is in play.
If it was only for the turn it was Summoned, it would say "When _____ comes into play,"
You can't prove that.
Ethersworn Canonist has a static ability. Static abilities describe rules or facts that are read and followed as applicable. To be applying a static ability is just to treat its text as true, barring cases of interaction of continuous effects.
Implicitly, a static ability is "always". Unless a static ability had a duration term like "the turn ~this~ enters play" (which would be really weird), a static ability is possibly relevant at any time.
"This turn" in that ability, no matter what turn it is, always refers to this turn, a.k.a. the turn that it is now. The ability tells you to follow the rule it describes: Each player who has played a nonartifact spell this turn can't play (additional) nonartifact spells.
Is the effect retrospective? For example, if your opponent has played a non-artifact spell before you played the Canonist, will you effectively stop him from playing any more non-artifact spells during that turn?
