I love that this Deck also includes a Super Villain like Negaduck, Public Enemy Number One as his ability is pretty handy to slow down your opponent

So getting out two or three Merfolk out ahead of your commander is actually a good thing, because when he's out, instead of Exploring once, you can do it multiple times

If you manage to end up at 13 life with all the life total manipulation Jerren provides, you can flip it into Ormendahl, the Corruptor, which will undoubtedly close the game in short order

Its interesting that you can attack with it and tap for mana later because it has vigilance, but unlike normal manlands, it stays as a creature, so its more vulnerable to removal
