With the addition of "Sonic Slip Garchomp", "Revenge Druddigon"  and "Marnie's Pride" from Brilliant Stars, Dragon decks gained 2 very strong attackers as well as a solid way to accelerate energy into play. These cards can seemlessly slide into current Dragon decks, especially since there aren't a whole lot of solid options to choose from thanks to Dragon Pokemon just recently being reintroduced into the TCG with Evolving Skies.

-----------------------------------------------------------------------------------------------------------------------

The Druddigon functions as an obvious revenge KO'er, with a second attack (Dragon Claw) that can still be functional with the help of Muscle Band or Fighting Fury Belt to be able to OHKO most Basic Pokemon.

While Druddigon is very solid, the real threat is Garchomp, now much more improved over the "Quick Dive/Royal Blades" variant that was being played previously.  Its Sonic Slip Ability allowing it to completely nullify effects and damage done to it by your opponent's attacks on the turn it evolves can drastically change the tempo of the game, barring your opponent uses some form of ability lock or some kind of push/pull/gust to get it out of the active position. The potential extra turn of invulnerability allows you to abuse Dragonite's Fast Call Ability to then further your board state in a multitude of ways, whether it's by:

* Use Guzma/Boss to knock out something important on your opponent's bench or chase energy

* Use Hex Maniac to prevent your opponent from further setting up or from recovering

* Use Gladion to grab something you may need from your prizes

* Use Lusamine to recover certain cards from your discard pile

* Use Marnie's Pride to accelerate energy into play, which in my opinion, finds a great home in Dragon decks thanks to how they usually need varying types of energy to attack. Using it on a free turn thanks to Garchomp's Sonic Slip Ability is the perfect opportunity to do so, especially when you can't use Raihan since presumably nothing was knocked out on that turn.

* A simple draw supporter to help dig through or thin your deck

The Muscle Band also bumps Garchomp's Dragonblade up to 180 Damage, which can get help it get over some of the bulkier Stage 2 Pokemon out there (e.g. Voltage Beat Rillaboom and Rear Attack Grimmsnarl's 170 HP) as well as 130 HP Basic Pokemon with either Cape of Toughness or Fighting Fury Belt attached to them. 

If you're worried about damage in general, you can also add the Stadium Devoured Field to add an extra 10 Damage to your Dragon Pokemon's attacks.

-----------------------------------------------------------------------------------------------------------------------

Since Dragon Pokemon require different energy types to attack most of the time, Professor's Letter is a great card to grab off of Raihan and/or Teammates, and if needed, Sonia can be searched via Dragonite's Fast Call Ability, so you have the ability to grab energy through various ways. Having easy access to a variety of energy allows you to combo them into the discard pile whether it's via Quick Ball, Mysterious Treasure, Guzma & Hala, etc. so that they can be used with either Marnie's Pride or Raihan.
