Theres a very specific combo that allows you to accrue tons of value by sacrificing Narfi over and over again
sometime.
2024-06-07 Umbra armor has no effect if the enchanted creature is put into a graveyard for any other reason, such as if it's sacrificed, if the "legend rule" applies to it, or if its toughness is 0 or less
Even in Limited Edition Alpha, the very first printing, the Samite Healer stood tall on the same battlefields where Shivan Dragons roamed the skies and Time Walks whizzed overhead
There are certainly cards that work fine with both and it can be done but you will either have stuff that does nothing with one half of your engines or you will have a pretty underwhelming Sneak Attack compared to what it can do
But all the cards mentioned above, apart from the Trainers, are actual Pokmon cards of their respective species, so hopefully I wont have to deal with any Pikachu with all kind of stamps in the near future
