The idea of this deck is to use your 8 dash creatures to relentlessly attack your opponent, generating goblin and spirit tokens. Mardu Ascendancy
+
Mardu Scout
or Mardu Shadowspear
+
Spirit Bonds
The theme of casting cheap creatures to increase the number of total creatures is continued with the other creatures in the deck, seven of which have death touch to serve as a deterrent to your opponent.
Qarasi High Priest, allows you turn those 1/1 tokens into 2/2 manifestations which trigger both Mardu Ascendancy and Spirit Bonds
Arcbonding an attacking deathtouch creature, with athreos can serve as a boardwipe, and huge health hit. Plus, if you clear a bunch of manifested cards, all of those can be returned to your hand. (assuming your opponent doesn't pay life)
Harsh sustenance can finish your opponent off as well.
On my list of cards to get is brutal hordechief and seraph of the masses. Are there any other cards that you would recommend for this deck?
I do have a couple questions for playing this deck however, should I be adding more burn/removal spells?
I am also really uncertain about the mana base, and ramp. I play mostly green decks that have their own ramp built in. Any tips would be nice.
