Basic Allies deck. Runs the best Allies to give bonuses each time another Ally hits the table. Tries to drop Harabaz Druid Buy and other cheap allies, like Hada Freeblade Buy, Oran-Rief Survivalist Buy, and Kazandu Blademaster Buy, early to get the synergy going. Once you hit five mana, drop Hagra Diabolist Buy, and then either cast Ghostway Buy for the win, or keep casting more allies, ramping up the life loss with each one.

Casting Ghostway Buy with Hagra Diabolist Buy and 4 other allies out will cause 25 life loss. With 5 others, you cause 36. With two Hagra Diabolist Buy and 3 others, you cause 50 life loss. If you can, try to cast Join the Ranks Buy either in response to the triggers that fire when Ghostway Buy brings your Allies back into play, or in response to triggers firing from another Ally hitting the battlefield (like from another Join the Ranks Buy). Remember, the triggered abilities count the number of allies you control when they actually resolve, so increasing the number of Allies you control before a trigger resolves can pump all your triggered abilities by 2!

Rounding out the deck, Kabira Evangel Buy lets you attack into colored creatures without fear, Tajuru Archer Buy can help you deal with fliers, and Aura Shards Buy can get rid of any pesky artifacts/enchantments that are hindering your game plan. Eladamri's Call Buy allows you to find the key Ally you're missing, while Genesis Wave Buy can combine with the mana from one or more Harabaz Druid Buys to flop out 6-10 cards and win the game from nowhere.
