Unstable Personalities

To get the obvious out of the way first, this is not a deck that's incredibly serious, so you might want to modify this before bringing the to Worlds or a similar tournament. This deck can hold its own on the Diamond ranks when played well, so it can be brought to ladder without much of a problem, surprisingly.

As for why I made this deck, Unstable Form is fun, and doesn't have enough love in most games. Even Elysian as a whole doesn't have enough love. While this deck isn't the best example of how powerful this faction can be, the deck showcases how fun this faction., and especially changing units into others, can be. Of course, you have to think when using transformation cards, so expecting free wins out of this (and the faction in general) isn't the best use of your time...

The first thing you should notice is that every single unit, bar Cirso, highly benefits from Unstable Form. This is particularly true with Magus of the Mist and Eilyn's Frostrider, both of which can turn a boardstate into something very wild, and can potentially turn games around on a dime. As for why Cirso is here... he's there as a big pig boy that does a ton of aggressive stuff. You can replace him with other good summon effects, such as Lumen Defender and Jerral's Frostkin for a less costly deck. This deck also attacks other decks by turning their units into other units. It turns out that if you turn a keystone unit into another unit, some decks start to fall apart at the seams. Do be on the lookout for weapons, though.

I also learned a few things playing this deck...
1.) Cobalt Acolyte is underrated, and actually quite versatile as a card. Even when you don't need a unit to fly, popping an Aegis is a very convenient effect.
2.) Eilyn's Frostrider is highly underrated. It has an effect that can swing a stable board right into a highly favorable position that you can push on. That that's WITHOUT the Unstable Forms factored in.
3.) Unstable Form is an incredibly goofy card, and just makes games a ton of fun when you can make tempo swings on a whim, I knew the card was very fun, but when it's doing powerful things, it can result in wild giggling.

While this might not be the best deck, it's a fun and functional deck, and if you're looking for a change of pace from playing the same units all of this time, this is a great deck to play.

EDIT: Set 4's here. The deck didn't actually change terribly much, besides a different board clear in the form of Cirso's Choice, and some cool units. I hoped Acquisitive Crow would be good here... nope. Bird's too awkward for most Unstable Form decks, sadly. Having access to Shimmerpack in the Market is sweet, though.
