Very interesting analysis of the new summoner. One place where I think someone can really take advantage of this card is when you see your opponent is often playing many camouflage monsters to hide in the back of their lineups... using the trample ability to allow your sneak attackers to hit the camouflage monsters will be a very strong play.

I also agree with your assessment about odd numbers, since that means no diemonshark or deeplurker for water team.
