Cool Card Design of the Day
4/25/2016 - I'm not entirely sold on Goldnight Castigator. It suffers double damage, but its toughness was doubled, so that ability doesn't matter. If it were red-white, the combination would be cute, but red doesn't do giant toughness, so it's just a poorly delivered joke.
I played it this weekend and against it, and Castigator cost its caster the game every time. Not surprising, since if you boil it down, it's a 4/4 haste flyer for four with a huge downside—a downside that red is least equipped to mitigate. It certainly compares poorly to Thundermaw Hellkite, for a mythic.
None of that is to say that the design goal or the flavor are bad… I love them both. Which is why I wanted to find an execution that does them more justice.
Goldnight Betrayer occasionally murders some unsuspecting creature she decided wasn't to her liking that turn. If the odds of being targeted were even (like Goblin Test Pilot), Betrayer would give you excellent odds when you're losing on the board. While that's an attractive idea, it doesn't convey frothing, violent, traitorous madness as well as this effect which is always more likely to target your own creatures. Even with that probability, Betrayer could potentially prove all upside in certain matches, which is exciting. Mistform Ultimus is excited. Just look at that… grin?
Maybe this wants haste and mythic rarity.
