For example, let's say you have Umara Wizard or Umara Skyfalls
Or you can just see how many copies of Archon of Cruelty it takes to beat your pod
Mushu, Your Worst Nightmare, giving one of your characters Rush, Reckless, and Evasive means you're able to send a tank in to wreak havoc and send your opponents' characters to the discard
Of course, mono-blue counters is a less than loved archetype, shall we say
While it still plays a part for those of us not willing to shell out the cash for the mostly superior options, it suffers both from not being able to selectively keep your creatures while killing your opponents' and from sometimes not being able to wipe out the creatures with tons of +1/+1 counters on them
I keep wondering where we go from here
