Quote from the nobodys »I really like Emry. While the ETB on her is not as good as goblin, being able to cast for U on turn 2 (like after an astrolabe and witching well) is really nice. And the ceiling for her ETB is even higher than engineer, so occasionally she will bin you a sword and something else useful. She plays well with bauble (no mana to get a card/turn), and unlike engineer, she can let you recur X cost things like explosives and chalice, and can recur stuff greater than CMC 3, although that is of questionable utility with our current builds. Definitely a 1-2 of in every build going forward, given her casting cost and lack of mana on her activated.
Wishclaw is a little silly, and hard to evaluate. I think it's probably a 1-of for us, but will get boarded out a LOT. Obviously makes whir more valuable, and random silver bullet type things. Talisman plays nicely with Karn, the Great Creator (ugh, that card), too. I've been testing Karn out as a 1-of maindeck walker without lattice, and he's OK as a must-answer threat.
As always, before the entire set is even released, posting a hypthetical list with the new tasty spoilers:
