Rotom ex #126 's electrifying design brings back the iconic trickster 'mon with an SIR it deserves, while Piplup #98 sees depicts of the cutest Pokmon sitting happily under cover, avoiding the icy weather: it's the most adorable card of the entire expansion
So every turn you can do 60 damage with Night Slash, switch with Sharpedo, retreat back for Gliscor next turn, Night Slash, repeat, etc
So when you sacrificed it, it would come back into play, and you could Thoughtseize your opponent again

summon your big boss multiple (king of the skull servant) create protection for it and put your skull servants and wight monsters into the grave to bost the damage of your boss monster, for the extra deck you can use linkuriboh and the fusion so keep them at 3, the rest are trash for the pot so keep them there, you can use other stuff that you have, you definitely won't want all the Dragonecro or linkuriboh to get banished , use the Dragonecro for OTK with your King since it make your opponent monster ATK 0 and summon a token to your field, use burial from the different dimension so you can return your skull servants, wight monsters to the graveyard after using there effect or the king's effect to reborn himself after be destroy by battle or card effects, you don't really need infinite impermanence but it's better to have a strong card in the deck but you should use pot as one of your main draw power

Its a fun way to weave them into the game play, as well as an interesting strategic choice
