WU Modular Affinity (Pauper)

This deck is a test Ive made and until now its been very effective either against Monoblack devotions and Delver/Faeries or Delver/Fiends.

The deck basically works combining the Modular base with Affinitys like Frogmite and Somber Hoverguard

Journey to Nowhere and Smite helps to keep the opponents table empty and Dawn Charm can either counter spells like the Diabolic Edict (And other sacrifices in Monoblack) or stop strong attacks from creatures you couldnt stop early.

In the Sideboard there is some tricks of mine =D
Mana Tithe helps against decks with low amount of mana (Like Delver/Faeries and Delver/Fiend).
Kill Shot Will help against creature based (This is where I need some help... I Thought about Unmake, but WWW is too much in my deck and I couldnt thought about anything else).
Curse of the Bloody Tome is a trick against a lot of decks that need candrips to work, specially Delver/Faeries. I won almost every game after this cheap beauty got in the table... =D
Blue Elemental Blast It doesnt need explain, right?
Curse of Chains Its also for creatures that could slow you down.

Thats it guys! Tell me what do you think about this deck and what could make it get better!

Thanks!
