This is a agroo-combo deck, Kaalia is so powerful that you can choose to win by damage, or even combo as a result of combats.
My Main strategy always is cast Kaalia of the Vast with Haste fast as you can and put her army attacking, but depending on the type of deck you are playing against, you should adopt some alternative strategy and for that, the deck has the combos, and the anti-combo part, to penalize opponents that combo faster than Kaalia.

>Combo Explanations

Kaalia of the Vast + Master of Cruelties:
Attack with Kaalia.
Kaalia's ability triggers enabling you to place Master of Cruelties tapped and attacking and make sure it's unblocked (Access Tunnel or Rogue's Passage take care of it, or used on Kaalia as well).
The Master of Cruelties' fist strike causes him to deal damage first and reducing the opponent's health to 1, then enter Kaalia's combat damage

Animate Dead or Dance of the Dead + Worldgorger Dragon
Cast Animate Dead, targeting Worldgorger Dragon in your graveyard.
Worldgorger Dragon enters the battlefield, exiling all other permanents you control.
Animate Dead triggers, sacrificing Worldgorger Dragon.
All permanents exiled with Worldgorger Dragon enter the battlefield including your lands enter the field untapped.
Target Worldgorger Dragon with Animate Dead.
Maintaining priority, tap all lands you control.
Let the triggers resolve.

This is the deck's main combo, generating infinite Mana and infinite ETB's, and with that we have the following ways to finish:
1 - infinite mana to cast Firebal, or Searing Touch
2 - Infinite ETB with any of these cards on the field:

Angel of Despair: destroy all permanents
Terror of the Peaks or Dragon Tempest: Damage when ETB

This combo can easily be responded to if Animate Dead is countered or removed, or the dragon is removed before the trigger to exile its permanents. Always keep an answer for this: Deflecting Swat, Silence, Red Elemental Blast, Pyroblast, Boros Charm or Flawless Maneuver protect your combo.
Or you can sacrifice Emergence Zone to cast in instant speed when all opponents' lands are tapped or all their responses are on stack.

Kiki-Jiki, Mirror Breaker + Zealous Conscripts
Activate Kiki-Jiki by tapping it, creating a token copy of Zealous Conscripts.

You can use Razaketh the Foulblooded to tutor rather than generate mana

Kiki-Jiki, Mirror Breaker + Worldgorger Dragon
Cast Kiki-Jiki, then Worldgorger Dragon.
Holding priority with Worldgorger Dragon's exile ability on the stack, tap Kiki-Jiki to make a copy of Worldgorger Dragon.
Allow the copy of Worldgorger Dragon to exile all your other permanents including the original one.
The original Worldgorger Dragon's trigger now resolves, exiling the copy of Worldgorger Dragon, triggering its ability to bring back all your exiled permanents including Kiki-Jiki and the original Worldgorger Dragon.
