That's no different from scope lens Kingdra in OU, which isn't really that good :wKingdra

Edit: I think Druddigon should be higher, prankster + mold breaker taunt gives you pretty much a guaranteed turn 1 stealth rocks whilst preventing opposing rocks from going up.
Reasoning: Every team that wants a rock setter in EI, wants one with mold breaker imo. Setting rocks on yourself due to an unexpected magic bounce can really turn the game against you. Mold Breaker + Prankster + Rocks + Taunt is the best way to prevent opposing rocks at the same time, and Drudiggon is the only mon that can get this combination.
Some other good choices for a Mold Breaker rock setter are Heatran, Skarmory and Mew. (I'm pretty sure Druddigon is best at it.)
Edit2: Prankster Mold Breaker Glare is also a good way to shut down many opposing sweepers in mid- to lategame that lack priority of their own. Think of Druddigon as a combination of lead Azelf and a Klefki that can paralyze Ground types.
