If you’re playing against a blue based control deck, that isn’t twin, you don’t even have to resolve scapeshift to win. You just have to ramp a bunch of mountains out, find valakuts either with primeval titan or naturally drawing them, and play lands until they die. I think the biggest problem this deck has is with fast combo and aggro. It runs no interaction mainboard and is just like a turn too slow for most of the fast decks in modern. The current version leans really heavily on its sideboard to shore up it’s bad matchups.

True. However, stack-based interaction is on a decline since the meta is really aggro heavy, with lots of Affinity/Burn/Zoo. So, the meta is favorable for this deck now.

If the meta slows down a bit, then regular/Bring to Light Scapeshift becomes a better choice.

Let’s see how Oath manages, Kozilek’s Return is a promising sweeper since it gets around Forge-Tenders and Etched Champions (though jury is up on whatever that’s worth 3 mana). Less aggro means more countermagic and Thoughtseizes, so it could go bad for it.
