Destiny HERO - Dreamer X DARK Level 1 [ Warrior / Effect ] ATK 0 DEF 600 During damage calculation, if your "Destiny HERO" monster battles and this card is in your GY: You can Special Summon this card, and if you do, your monster cannot be destroyed by that battle, also you take no battle damage from that battle
The part where destroying 1 monster if a S/T card is destroyed supposed to be a combo with "Harpies Hunting Ground" on the field, this card SS a "Harpie Lady", then "Harpies Hunting Ground" destroys a S/T, and finally this card destroys a monster on the field
You could even flicker this for more Voids
Personally I don't see the problem with this format
Unfortunately, most dual and tri lands have some drawbacks as a tradeoff for the power they provide
You Didn't Need That, Did You
