the big question in regards to whether this combo is good enough or not is if Rush of Dread is good enough without a Bloodletter of Aclazotz on board
You'll most likely see the ability coming (watch out for Lightning Greaves!), but The Cauldron of Eternity can be yours for a mere 12 life
On average, many attacks that deal at least 100 raw damage, especially from Basic and Stage 1 Pokmon, often come with downside, such as discarding energy ( Genetic Apex "Mewtwo"), dealing recoil damage ( Genetic Apex "Arcanine"), simply having extremely high cost ( Extradimensional Crisis Guzzlord ex, Shining Revelry Charizard ex), cannot be used twice in a row ( Extradimensional Crisis "Buzzwole"'s Big Beat) if not flat-out disallows its user to attack next turn (Hyper Beam and Giga Impact found in some Pokmon), and some other drawbacks ( Celestial Guardians Kommo-o takes extra damage after using Clanging Scales, Mega Rising Cofagrigus's Soul Shot requires you to discard 2 cards)
Why is he always so coveted
In other words, both sides of the market are repricing Violet ex upward, even if each venue prints a slightly different executable price
I just really liked how the deck was positioned
