================
Just a few questions to the group at large:

- Is Sinkhole a viable way to constrict our opponents resources (as opposed to Hymn)?

- Is playing a pair of Thoughtseize along-side Stifle reasonable? (I assume you have to wait till T2+ to TS if you have Stifle in hand) - tempo vs tap-out type of plans

- Thoughts on the basic Island and Swamp as ways to overcome the mirror/Wasteland decks? -- I've had poor results with basic lands in Delver shells historically, but this one is basically just two color so might be a different story.
