Zephyr's infinity toolbox

The main idea is discard some Lackeys or 2-cost cards (Zephyr is... GREAT! :p) and the Soulwarden, then play soulwarden and (if possible)Zephyr, endlessly.

alternatively, if the plan got screwed, you can discard one 3-4 cost card like Lifedrinker or High Priestess Jeklik or another combo you want
