I would try to get Umbreon into the game early on so you can start confusing your opponent's Pokemon, but if you can't get it out early, I would recommend putting it on your bench, attaching three energy cards to it, and waiting for your opponent to put a Pokemon with a lot of energy cards attached to it in the active Pokemon spot, I would then move Umbreon into that active Pokemon spot and use Shadow Shutdown until Umbreon is knocked out or retreated, I would hope to get lucky and flip 2 coins so my opponent would have to discard all their energy on that active Pokemon
This has implications not only in EDH, but also against control decks in Standard, for example
Adventure Dragons The Adventure Dragons are really what made me super-excited about this deck, letting me shave slots Id otherwise dedicate to noncreature interaction for the Adventure spells, and then have the Dragon side to cast later
Proponents of two-mana ramp argue it provides early mana fixing in decks, which allows you to cast a wider range of your spells earlier
But not without strings attached
Blacephalon costs 400 Pack Points to craft
