Rush lets a Digimon attack the same turn it hits the board, skipping the usual wait. That's damage your opponent couldn't see coming a turn ahead, which is exactly what aggro lines want. Put Rush on a body that also carries Security A. or Piercing and one memory swing can close a game.

asked about Sealsdramon (EX3-049)
When effects play multiples of my Tokens and/or Digimon with the [Puppet], can I use this card's <Your Turn> effect to give <Rush> to all of the played Digimon by suspending this Tamer?
No, you can't. You can only specify 1 Digimon that will gain <Rush> from among multiple Digimon that were played at the same time.

I used [BT16-091]/[Beastly Storm Dance of Affection]'s effect to DNA digivolve into this card, then I used [BT16-091]/[Beastly Storm Dance of Affection]'s effect to attack. At such times, can a Digimon played using this card's <When Digivolving> effect gain <Rush> and attack?
Because [BT16-077]/[Dinobeemon] is already using [BT16-091]/[Beastly Storm Dance of Affection]'s effect to attack, a played Digimon can gain <Rush>, but it can't use this card's effect to attack.

If I use this card's effect to play a Digimon from the trash, then digivolve that Digimon during the same turn, does that Digimon gain <Rush>?
Yes, it does. Digimon that gain <Rush> from this card's effect keep it after Digivolving, and can attack the turn they come into play.
Ruled Mar 28, 2024 · asked about Anubismon (BT4-087)
A Digimon has <Rush> thanks to this card's inherited effect. If that Digimon digivolves into a Digimon with a different name, can that Digimon attack the same turn it entered play?
No, it can't. The Digimon loses <Rush> when its name changes, so it can't attack.

What happens if this card's effect activates for my [Marcus Damon] that's treated as a 12000 DP Digimon with <Rush> due to [BT13-020]/[ShineGreymon: Burst Mode]'s effect?
The DP is overwritten by the effect that activated afterward, therefore the card is treated as a Digimon with 3000 DP. The <Rush> gained from [BT13-020]/[ShineGreymon: Burst Mode]'s effect remains because it isn't overwritten by anything.
Ruled Mar 28, 2024 · asked about Agumon (BT13-008)
After using this card, do level 6 Digimon with the [Machine] that are newly played or digivolved in the same turn gain <Rush> and <Blitz> from this card's effect?
Yes. The effect applies to all of your Digimon that meet the conditions, therefore this effect will also affect Digimon that later enter the battle area as long as they meet the conditions.
