I get it, these are popular Pokmon, but it just seems a shame
Where to Play Mangara
(This card is always treated as an "Archfiend" card.) Red-Eyes Black Flare Dragon X DARK Level 7 [ Dragon / GeminiEffect ] ATK 2400 DEF 2000 This card is treated as a Normal Monster while face-up on the field or in the Graveyard
If you want to open packs for fun, play draft or sealed, build a collection over time, or just enjoy the experience of cracking packs and seeing what you get, play boosters are designed for exactly that
On the other hand, if Genasi Enforcers is renamed Dark Genasi Enforcers, its ability "Creatures you control named Genasi Enforcers get +1/+0 until end of turn" will no longer affect itself, because its name is no longer Genasi Enforcers
That said, would I change anything about them
