I love being able to throw in a common like Impact Tremors which can take your infinite ETBs and only need as many triggers as your opponent has life
Theres a hard token strategy with this preconstructed deck, with an emphasis on Clue tokens, but also just lots of ways to draw cards and accrue incremental value throughout the game
You can also run the thematically appropriate Leonin Relic-Warder and Animate Dead combo alongside this nightmare, slotting in death payoffs that give you mana (Pitiless Plunderer) or life drain (Zulaport Cutthroat)
You can't self-exile, and you need five targets, it doesn't say, "up to five." But you should be able to at least recur it once, if not more, over the course of the game
With powerful abilities, devastating attacks, and breathtaking artwork, these cards represent the pinnacle of what the Pokmon TCG has to offer
