i think you need Hero's Downfall or some kind of removal for non enchantment creatures

Cost too much (5$) and i made this deck with cards from Journey into Nyx only (except the gates). But thx for the suggestion. It would be a nice add, but too expensive for me.

You're right for the removal. I need somthing else... Maybe Doom Blade will be a better choice (Still standart, can kill almost any creature, cheap). Still, i try to stay in Journey into Nyx.. :/ i'll try to find something else :) Thx!

Is there a particular reason you want this to be just journey? And you might consider being more aggressive with constellation. Also, have you considered Eidolon of Blossoms or Doomwake Giant? They make a nice high end to the mana curve, since you haven't included anything +3.

I make some change. You are right with Doomwake Giant , it's a good add. But i can't add Eidolon of Blossoms , cause it cost too much. I want to stay in a budget deck. In the other hand, i can add 2 Eidolon of Blossoms if i take off Pharika, God of Affliction ...

What i should do?

What about Dictate of Erebos ? Trigger constellations and then make your Pharika tokens and Chosens become two-for-ones.

Yea, that can fit really well in the deck. Still, 2$, and i don't know what i can take off for it. I prefer to add Eidolon of Blossoms before.
