That was an example of the dangers of using predictable movesets, overused pokemon for the tier, and common pokemon combinations. I was confident that you would switch in a Mismagius on the EQ despite not yet seeing it, and standard SD Venusaur gave me a free switch as well as a free attack on a predicted greedy Nasty Plot. Setting up early game is typically extremely risky.
Good game, but unpredictability is very important and decided this match.
