DESCRIPTION
soul warden + saffi eriksdotter + crypt champion = infinate life.
golgari germination + saffi eriksdotter + crypt champion = infinate creatures.
for those who don't understand the loop, this is how it works:
1.)sac saffi targeting soulwarden
2.)play crypt champion
3.)return saffi to play
4.)don't pay 1 red mana for champion
5.)sac saffi targeting champion in response
6.)champion dies as his triggered ability resolves and returns to play when saffi effect resolves.
With soul warden out you get infinate life, with germination out, you get infinate creatures.
fallen ideal and the husk are another win condition with the infinate tokens to give you an infinatly huge creature.
The castigates are used to get rid of any type of burn or creature disruption that could stop the combo.
