This is two really awesome abilities, which don't really have much in common. (Although the first one does put better cards in your hand, I guess). I suggest splitting them onto two cards, to savour the impact. And make it cost a bit more.

And testing the heck out of whether it's safe to not need to put things into play to use them!

Oh, and this is so mythic it's just not true.

But wow; such a huge pair of massively powerful abilities! Very cool.

Oh, that second ability is meant to mean that activate abilities of cards in your hand that have abilities that can be activated from hand - at instant speed. I mean, how would that even work otherwise - like for tap costs and such?

So, both of them are made with the proclaim mechanic in mind.
1) Put proclaimed cards from hand on top of library so theY can be "reproclaimed" once drawn.
2) Proclaim (forecast) whenever.

I think the backwards compatibility with Forecast is a little unnecessary, since Forecast is unlikely to be used again and the only forecast card used even semi-regularly is Proclamation of Rebirth. Because right now, the rule of "you may activate abilities (of cards in your hand) any time you could cast an instant" is already a rule, so to a person who just opened a fresh booster pack and got this, it seems odd that a card would just state a rule that's already in place.

­Leonin Shikari and Ninja (the augment card), though much more narrow in application, spell out the fact that it applies to certain abilities that are only activated as a sorcery to get it to read better. I think the same should be done here. The other issue with forecast is that forecast has different timing clauses than "any time you could cast a sorcery", which open up room for confusion.

Also totally missed that you can Brainstorm proclaimed cards to redraw them later to proclaim them again. I like and dislike the fact that the set will force people to think of the hand more of as a zone akin to the graveyard or battlefield than normal.

Mmm, true; it only allows you to use abilities that don't tap or sacrifice. There's still a few of those to go around. Heck; I think it It'll allow you to cheat equipment into play without ever casting it.

If all it means is "at sorcery speed restriction is lifted" then that's a heck of a lot less interesting. (And is still probably unprintably confusing)

Yeah, the second ability would need to be reworded to remove ambiguity e. g.

• "Activated abilities of cards in your hand that you can activate may be activated any time you could cast an instant."

Maybe? I think a less "awe-inspiring" ability is fine since this is already plenty tricky and the alternative requires beind extra sensitive to each other card this could interact with.

Instant speed transmuting seems legit.

The second ability started out as

> You may proclaim any time you could cast an instant.

What are your opinions of this? Is the backward - and forward - compatibility worth it?

One reason why I didn't make it just proclaim was that it feels a bit weird in a card that can't really utilize it itself. As in, this doesn't have proclaim or anything.

Eh, I'll change it back to that ability being restricted to proclaiming.

I think this falls into the rare category of "how can I break this?" rare. If I am unfamiliar with the set and I open this card as it is currently, my thought process is likely to be:

"What does proclaim mean?" -> Look through pack for "proclaim" -> "Oh, nice, I see why this would be useful and fun to break"

Whereas if the card used the previous text:

"I thought you could always activate abilities any time you may cast instants?" -> Look through pack for activated abilities -> See proclaim -> Proclaim = activated ability from hand -> "Oh, nice, I see why this would be useful and fun to break"

There's a lot more opportunity for the player to miss one of those steps and just give up on understanding the card, as I see new players often do.

While the cross-block compatibility is tempting, I don't think it should be done while sacrificing readability. Activated abilities from hand are rare enough that I think that players won't be able to immediately understand the ability in its previous wording well. It ties back into my belief that many players don't think of the hand as a traditional zone.

Aww, shame. I'll go stick the original (horrendously broken) version in my silly set, then :)

I just noticed that the reminder text implies that proclaim is a special action rather than an activated ability. So it's probably better not to mention activated abilities on this one.
