This is the deck that got me to diamond II this season. Masters was reached with a TJP brew.
This deck works wonders against aggresive lists and is only truly vulnerable to control lists with too much removal. The goal was to make this deck pack as many valkyries as possible.
Rolant's intervention is mainly used to save your valkyries from removal spells
Scavenger resurrects you valkyries
Icaria ramps you
You mainly want to survive long enough against aggro until your lifelink creatures or weapons arrive.
For midrange you want to keep your vanquishes and enforces to kill and silence their creatures, such as darude and behemoths
Against control you'd ideally want them to waste removal on smaller threats, don't commit more than 2 creatures on the board and save your aegis for Amilli or Makto!
