if you want it to be better against burn id put cards that add to your curvatures toughness or industractable cards

Titan's Strength

4x Ethereal armor?

I have a very similar deck. One thing that I felt kept falling short was the sheer number of creatures. I've upped that amount to 21, but here's what mine looks like: Hero's Triumph

You might consider replacing the Lightning Strike's with Magma Jet in order to control your next draw with scrying.

@ Mongol,

Magma Jet can indeed be used instead of Lightning Strike but the trouble i am having with is lies more with the fact i end up against mono black removal or mono blue bounce and noticing that they just swipe my big creatures before i can kill them, so i thought of replacing Gift of Immortality with Indestructibility and mainboarding that enchantment. that will give me more resistance to black removal.

If you are worried about more kill spells I would add Brave the Elements or Rootborn Defenses . Maybe even Ajani's Presence when JOU comes out.

I think you could benefit from a few more creatures, like Fabled Hero or Fencing Ace . A third creature that I like with heroic is Phalanx Leader because he can pump up all of your creatures.

You might also want to remove the Temple of Triumph because a tapped land can slow you down a whole turn. Maybe add Sacred Foundry or Mana Confluence (once JOU is out).

@ EKGwins

I am currently searching Sacred Foundry 's to replace the temples of triumph. I am considering taking some JIN cards like Ajani's Presence but i will not add more creatures in the main board. i might add some in the sideboard for when i have to play against serious removal. replacing Searing Blood with Fabled Hero or Phalanx Leader
