Lady Tremaine, Imperious Queen Wickedly good Cinderellas wicked stepmother puts her fearsome presence on full display in ruby Rise of the Floodborn card Lady Tremaine, Imperious Queen
My favorite double-faced villain is Ultimecia, Time Sorceress, which has an ability we'd normally never put at uncommon, especially on a creature: an extra-turn effect
They help to keep them in good condition
It also keeps Hydro-Man safe from sorcery-speed removal and board wipes, though it removes it as a blocker, so theres some trade-off for your forbidden blue ramp
But more importantly, if your opponent allows you to untap with a Hullbreaker Horror , it'll soon sink their spirit as well as their ships
If you want an extra method of protection, use double card sleeves
