Overall, Aura of Courage is a powerful but fragile deck
Having a land turn into an imposing flyer in the late game is incredible
Tazri, Beacon of Unity is solid, but with only a handful of Party cards in red and green, five-color really isnt necessary
The Grixis color combination isn't great at ramping mana, but vampires tend to be very efficient in their cost and rely on each other for benefit, besides, you are limited to casting one collected card on each player's turn, so it's not broken right
Original Planeswalker Cycle The first five planeswalkers ever made were Ajani Goldmane, Garruk Wildspeaker, Liliana Vess, Chandra Nalaar, and Jace Beleren
Every player gets to draw two additional cards, but if you're piloting a deck that churns through cards at lightning speed, you're set to benefit the most
