The Snake TISUIYLAIYWD

Whenever The Snake TISUIYLAIYWD blocks or becomes blocked by a creature with fewer letters in its name, destroy that creature at end of combat. (Punctuation and spaces aren't letters.)
Whenever an opponent reads Stone-Cold Basilisk, that player is turned to stone until end of turn. Stoned players can't attack, block, or cast spells or abilities.
"The snake that is so ugly that if you look at it you will die." —A warrior that speaks from the grave.
