Rook
Brief Discussion
Rook is generally considered among the weaker of the characters. Despite having a really damaging super throw in Checkmate Buster, he has no dodges and therefore can’t threaten a true mix-up with it. He also has really bad losing matchups to 
and is extremely safe to gold burst against.
Most of the changes that have been discussed are directed towards his special blocks, as they tend to be viewed as the weakest part of his kit.
Consensus Changes
Having his special blocks return on Block/Blodge (just like Gwen’s 10*) can be considered a much needed quality of life/intuition fix which also gives him a mild buff. The main balance fix is for both 3* and 5* to end Range, (reworked) Temporal Distortion and (reworked) Bubble Shield . Gold Burst is still safer against Rook than any other character but his 3* will now beat it.
These special blocks now explicitly revert to normal blocks when countered, which drastically improves his match-up against and gives a mild-moderate buff in his match-ups vs 
3* Entangling Vines [During Combat]
When you block an attack or Joker with this card, take no block damage, discard this card, and don’t draw a card from blocking. Hit the opponent for 5 damage and knock them down. Next turn your attacks and throws are 3 speed faster, to a minimum speed of 1.0. (If this ability is countered this card reverts to a normal block)
5* Stone Wall [During Combat]
When you block an attack with this card, take no block damage, discard this card, and don’t draw a card from blocking. Hit the opponent for the damage their attack would have dealt if it had won combat. (If this ability is countered this card reverts to a normal block)
Changes Under Consideration
Suggested by everybody’s favorite Rook main, changing 9-throw to a 9-attack is designed to improve the max damage of Rock Armor, improve access to straights, and give Rook a credible (and scary) knockdown mixup with both even and odd normals.
It has been well received so far, so could almost be considered consensus, but it needs at least some testing to make sure it doesn’t break anything
9-throw —> 9-attack
