First card ever that mentions the phrase "keyword ability/ies"?

why not just give it all abilities? Think of the mayhem :)

Granting CDAs is a no-no. What happens if you plug together Maro and Nightmare? Previously it was only possible with S.N.O.T. and temporary copying (Mizzium Transreliquat), which is why I call it a Maro-Nightmare, but that would do it too.

Restricting to keyword abilities avoids that problem, but it has its own problems. Basically, almost nobody knows quite what's a keyword ability. Is "protection from Kavu", "~ is unblockable", "Threshold - ~ has flying", ": Regenerate ~"? I know the answers, but most players won't.

The fact that indestructible has just changed categories doesn't help; nor does the way that some old cards have keyworded "fear" and others have non-keyworded "fear", and similarly lifelink; while spelled-out keywords for vigilance and reach have been granted via errata.

you just gotta consult the rulesbook like other clones, ie necrotic ooze. did you know cycling is actually an activated ability?
