Counter Catcher is undeniably one of the strongest cards from Paradox Rift. As an Item card, it allows for advantage-swinging combo plays that include the effect of a Supporter card, to be executed by any deck that expects to fall behind on prize cards in the early game. Among the traditional prize-trading decks, Gardevoir ҼX and Giratina 𝙑sᴛᴀʀ stand to benefit the most, as they can incorporate Counter Catcher into their existing comeback combos. Irida and Arven-focused decks can also include it to increase their outs to a gust effect if they ever fall behind. The strategy that truly gains the most, however, is one being brought from relative obscurity to the forefront of the metagame: Stall.
The Snorlax-based Stall archetype that’s become popular in early Paradox Rift tournaments has a simple premise: trap an opponent’s Pokémon that can’t threaten Snorlax in the active spot, and wait until your opponent decks out. This strategy is especially potent in the current format, due to the variety of support Pokémon decks are built with, to meet the demand for hyper aggression and winning as fast as possible. And according to data from online tournaments, Snorlax Stall’s win rate is far better than any other deck’s in the format.
On the surface, this seems like a fairly linear strategy—one that’s highly matchup-dependent and one with limited counter-play. When you take a closer look, however, there’s much more depth to the strategies used by Snorlax, and to counter it. And while its true matchup spread may still be impressive, it contains a couple more holes than online tournament data suggests.
Here’s a reference list for Snorlax Stall that you can use as a guide for the following discussions.
