You might be wondering “why would I use Onix-GX (Hidden Fates) in a stall deck when there are Pokemon with more HP and higher damage output?” The answer is simple: it’s funny.
At first glance, Onix-GX isn’t the best stall Pokemon. It only has a modest HP of 200, but we’ll remedy that later.
One of the most important aspects of this stall deck is the card’s “Bind” attack.
For one Fighting Energy, Onix-GX does 30 damage and if you flip “heads,” your opponent is paralyzed.
The goal of this deck is to keep your opponent paralyzed and soak up as much damage as possible while they exhaust their resources and inevitably deck out.
How are you supposed to soak up damage with only 200 HP, you ask? Fortunately, Onix-GX has a retreat cost of 4, which allows it to utilize Buff Padding — giving Onix-GX an additional 50 HP.
Onix-GX also has its own Stadium, Brock’s Pewter City Gym. With Brock’s Pewter City Gym on the field, Onix-GX takes 40 less damage from attacks.
But it’s not enough to rely on a coin flip to keep your opponent paralyzed. That’s why this deck uses Will, which lets you chose the outcome of the next coin flip on your turn.
While you’re running Will, you can also run Super Scoop Up to effectively erase even more damage by scooping a heavily-damaged Onix-GX.
Of course your opponent can switch out, right? In order to force your opponent to exhaust their Switch cards, run a few Great Catchers.
Great Catcher will also let you pull up a beefy Pokemon and stall even more time.
Use Crushing Hammer (also good with Will) to make sure retreating is not an option for your opponent.
These cards didn’t make the final cut, but they might work just as well in this deck.
Lusamine allows you to bring back important cards like Will and Brock’s Pewter City Gym.
Green’s Exploration is another option — with Onix-GX not having an ability, Green’s will let you search for the plethora of trainers in this deck.
