The item in question was a Team Rocket-themed pack: an expansion line from the early 2000s that featured cards inspired by the unscrupulous Pokmon-stealing organization from the video games and TV show (prepare for trouble...and make it double!)
The best approach is to constantly play cards while trashing unnecessary cards using "OP02-070 New Kama Land" and "OP02-065 Mr.3(Galdino)"
You have kind of the opposite motivation to something like Sydri, where you want mana-intensive artifacts to animate
The front side is a pseudo-one shot Reidane, and if you can grab the Wrath, then it buys you time to hit the flipside, which then protects you from it
Theoretically, you shouldnt put those cards in your deck, but sometimes the advantage they provide is far too great to ignore
