a possible variant would be cutting unstoppables, and on relying on playing card poison, and going with full set of sundials, maybe mark of light
the problem with the deck is, while it's win percentage is nothing to throw away, you lose to slow, just played 10 matches, won 6 of them(original build) but 4 loses are next to 2 minutes
edit: why extra posion doesn't work without a point of attack?
