I'd tend to think of it as a ***potential*** SB Card vs. Control and the mirror. I view it more as a 4cc card that does 5 to the face only - main reason being that we have no real 2-drops in the deck, so I definitely wouldn't mind opening t1 tapland t2 Font. 4 mana is a lot, so I like it better post-board when we (I) have 24 land available. It's probably weaker than T/T, so question is whether we will have room for it in our SBs. If control becomes dominating, probably yes - if the meta stays balanced (which is what I believe), then no.
