Gladion's Final Battle 118/84 Loading
This deck has some interesting decision points and isn't a linear strategy, but it's also not the most complicated out there - and that's important for a beginner deck
O-Nami can be played on turn 2, giving your Leader Banish before he attacks for 7,000 or more Power
This adds three power to the board the turn it comes down, and it will always be really enhancing your attacks, which is exactly what you want to be doing in RW, a color pair all about aggro
This includes generating more Energy, flipping coins for massive damage, or hitting every spot on your opponents side of the field
Decks with proactive, aggressive strategies primarily use noncombat damage to target the opponent
