Even though crowd control would be one of my selections for this category, I have already discussed it at length. (Yes, I am sparing you more Enchanter tales!)
Instead I will regale you with my other favorite strategy, the total opposite of crowd control, ZERG!
Zerg (of course!) comes from the real time sci-fi strategy game StarCraft and is the name of one of the three playable races. They are the creepy bug/alien option whose main purpose is to traverse the galaxy and biologically assimilate other species. Yuck.
What made the Zerg so fun was their ability to quickly create a whole lot of small units; the goal was to overwhelm your opponent before they had the opportunity to really get up and running or to simply overpower them with superior numbers.
Since I really enjoyed the creating of units and supervising buildings far better then micromanaging battles, this strategy was by far the most fun for me, which made Zerg my go to race in the original StarCraft. (StarCraft 2 changed Zerg to be far more micromanagement heavy, so I tend to play Protoss.)
From this ‘overwhelming’ strategy was born the term Zerg, which now means ‘overpower with superior sacrificial numbers’ in almost any setting, aka FUN!
