or more detection counters.
Whenever an opponent gets one or more energy counters, look at the top card of that player's
library. You may exile that card face down. If
you do, put a detection counter on Aether Virus.
{t}: Target opponent gets {e} (an energy counter).
The less the Consulate knows, the better.
