Tier 1
TPC Comments
Resonators remain the Deck to beat in the format, and will most likely remain so until the next BOX adds to the card (and Skill) pool.
Tier 2
TPC Comments
With the recent addition of Loading... , Crystal Beasts got a new powerful tool to make Loading... unaffected. To make Super Dora, the deck uses Loading... to search Loading... (which can modulate Crystal Beasts to Level 10). This gives the deck a protection from cards like Loading... (especially if you have a chainable Crystal Trap to work around Droplet's non-response window).
Crystal Beasts have a lot of tools to disrupt opponents with endboard pieces like Super Dora, Loading... and Loading... .
Super Dora also protects from Loading... , so the HERO matchup is no longer as bad as it once was. When it comes to other matchups, you can usually brute force your way to victory (especially going second).
The addition of Loading... allows Crystal Beasts to protect its Loading... without using Loading... (which requires a much more limited board). The deck also has a variety of Extra Deck monsters to make, like Loading... for Resonators and Predaplants and Loading... /Loading... for generic utility.
With the release of Loading... , Crystal Beast is now better. This is because it solved most of its problems with its first turn (no longer needing to rely on the Sky Striker cards to play against HEROs). Additionally, since the deck can do well going second by using Crystal Radiance and the Knightmares, I believe that it's correct to raise its spot on the Tier List.
