Emrakul, the Promised End Playing Emrakul, the Promised End in a colorless deck doesnt allow you to take advantage of its first ability all that much
Of course, all this power comes with some caveats
Theres a few cats with removal as part of their enters abilities, and you can use cards like Elesh Norn, Mother of Machines to double those triggers
Take the Shining Raichu list, for instance
Products that won't transfer over to Pokemon TCG Live at all include all cards from the HeartGold & SoulSilver series, which is basically a death sentence for the Pokemon TCG Online -exclusive Legacy format
I see this card being a sweet inclusion to Orzhov Lifegain lists like Karlov of the Ghost Council, Ayli, Eternal Pilgrim, and Regna, the Redeemer & Krav, the Unredeemed, decks that can properly use their own life totals as a resource to exploit (hello, Aetherflux Reservoir)
