After running into both the Calm Mind Life Orb and Substitute Calm Mind sets, I conclude that both of them are monsters.... total monsters. In fact, I have serious trouble countering them until I started testing my own Calm Mind Life Orb Raikou (which still 2HKOs even after the first Calm Mind). What makes the Sub set so deadly is that electric and grass attacks are fairly rare, and you beat the most common grass type Celebi with it, and you can't explode on it because it subs in your face and is suprisingly faster than the majority of boomers (all except Gar and Zelf really). The Life Orb set is a total bitch to handle because after its first Calm Mind its type coverage and power are very difficult to deal with (worse than life orb Starmie and sweeper Deoxys).
