The way I see this is this is basically Sinister Serpent, but requiring that you perform your Battle Phase first
Such is the case in Pokemon TCG Pocket, where all of sudden, every opponent you face in 1v1 seems to have the same identical deck: two Mewtwo EXes, two Gardevoirs, and maybe a Chansey that they barely touch
1 x Token
Additionally, a trading card template can be helpful for those who may not have as much design experience, as it provides a structure and guidance for creating a visually appealing card
As far as combat tricks go its not a great one, but it does make any creature basically immune to damage for a turn and it gets the job done by being very cheap
Each structure deck includes: 5x Ultra Rares, 3x Super Rares, 38x Commons, 3x Token Cards, 1x Double-sided Deluxe Game Mat/Dueling Guide
