(A gold token, however, we're not going to explain at all. Presumably it's a multi-coloured object with no colours, type or controller.)

@Vitenka: A token has always been a permanent - with no type given it might be one of those typeless permanents rather than just any object. The create action is also clear under whose control it creates the token, so no reason to assume that would be different than usual.

Gold is also apparently a subtype, so maybe this is an experimental template where players are supposed to know the card type associated with each subtype by heart? At least "no colours" seems right - but colorless permanents are nothing new.

Lol, doesn't everyone know what a Gold token is? Anyway, the point was to test out the evasion ability reminder text.

A weird one-off mechanic from a set I didn't play? No, I don't know it.

Anyway; I dunno. I dislike this on two fronts - thematically (what do 'menace' 'protection from' 'flying' and 'you must pay 2 to block this creature' mean in common that cold trigger something?)

And mechanically - what does this actually add beyond normal 'hit the opponent' triggers? That would seem to cover all of the same space, apart from "My opponent actively chose to let me"

For phrasing though; would "Whenever an opponent is unable to block..." work?

Lol, doesn't everyone know what a Saproling token is?

I hate that Gold has become a predefined token now, but I guess that means this is closer to working
