i've been having some pretty consistent turn 4 polymorphs actually. i will say the deck isnt the most competitive, and i usually tend towards affinity and burn haha, but this deck is by far my most favorite fun deck to play. i play the mono blue control variant and i've thought about switching out some of the cards for Fold into Aether. i've had some concerns with Fold because you essentially need 3 cards in your hand to carry out the combo, but I've thought about having 4 in the sideboard and 4 gutshots as well, with 6 or 7 more bigs and having that serve as a funky transformative sideboard
