I'd like to see a few more proactive counters. Right now, it usually feels like everything is reactive in Elements. There are a few proactive counters, like playing Sanctuary before black hole or silence, or playing a reflective shield before a firebolt, or protect artifact/quint vs PC/CC, for instance, but in general, it feels more like you have to respond to threats rather than have something in advance. For instance, basically all PC/CC right now is reactive, although you can count shields as a sort of proactive CC. An example of proactive CC would be something like a permanent that deals 2 damage to the next creature that comes into play and is then destroyed.
