I actually enjoyed the slower pace of The Witness. Even the water level puzzles.

Sometimes just taking your time is nice. (But I understand it's not for everyone.)

I was looking at Iceridge Serpent and thought, with the art and the giant sea serpent flavour it could also have bounced vehicles which didn't really fit Tarkir but could have played well after Aetherdrift.

Assassin's Creed was okay this year with an artifact/equipment boros deck and an assasin freerun dimir deck. But like the set, it was a weird matchup flavour wise.

Bloomburrow was disappointing with a very good Selesnya rabbit deck that steamrolls the izzet otter/spellcast deck nearly all the time.

It's a product I really love conceptually. Two decks meant to be evenly matched up with one another, meant to learn the basics with just a few twists for interaction.

I buy them as soon as I can. I don't like that they put exclusive cards in them.
