No savannahs so he never intended to use wane. The only thing I can think of is that against a Pikula gives a card that is unexpected. The reason I think WW was so prevalent is because the deck is stable and versatile and against an undetermined metagame those 2 virtues are very important. You don't want your deck defeating you.
