These sleeves minimize surface scratches and damage to your cards during storage, display, or, for gaming cards, during gameplay
"Removal" can also apply to hitting other permanent types, but in the MTG community, "removal" usually means taking out creatures
As such only really combo and control decks run this
The fact that you can Special Summon a monster form the Graveyard is already powerful, so, again, conditional
I can confidently say that in both flavor and mechanics, this deck looks insanely fun to me
