Counters Not Being Added
While playing with my enchantment deck (standard), there were times when certain counters weren't being added when they should have been. For example: I had a Generous Visitor out and cast an Enchantment card. Generous Visitor rule triggered, but when I selected a target creature for the counter, no +1 counter was added to that creature. No counter was added at all.
Was Vorinclex in play?
