I think that an important aspect of Merfolk is their ability to grow. IF you have the focus of the deck be unblockable, untouchable merfolk then your deck will be a greater against your opponent. Just keep in mind that if your opponent can't block your creatures then they will try to use destruction spells against you so keep in mind any wrath abilities they may have. Counter spells will shut down your opponent's back up plans and could secure you some wins. What are your thoughts on this?
