Very small for a mythic creature. Mythics are generally "square stats", i.e. P and T each equal to their CMC. This creature can certainly be bigger, given that you can't use it to attack and also make a pile of tokens on the same turn.

Otherwise, this is good; the ability on a hasty creature is both fun and powerful enough for mythic.

I assume the type line indicates this character is a half-breed?

I want to address your comment that Serix doesn't value out, or is too small, but you'll need the following first.

The story behind Soradyne Laboratories (the set) happens shortly after a huge and unexplainable event of military and political importance: the most cutthroat and dangerous army in the world just packed it in and went home, mere hours from winning a battle that would have garaunteed world conquest. As such, the people are left with no real villain, but tons of questions. There are no obvious grand battles to be fought here, no immediate ascending despots to challenge, just the perception of a lot of unanswered loose ends.

The big picture then is one where there are a lot of rumors and partial explanations, many players with unclear involvement, and lots of people who want to know the truth.

Serix Thames is a half-elf hotshot reporter. Ladies love him, men want to be him. He's the most popular news writer in all of Debronia, and he's clearly the king of adventure journalism. He's also determined to uncover the truth of the mysterious retreat of the enemy.

He's a civilian. He's the face of the media, and he attracts followers who want the truth almost as much as he does. He's got no martial background save relatives who've fought in wars, so he's not meant to be any kind of fighter himself, just a royal pain in the ass of anyone trying to hide truth or subvert the masses. He uncovers stories and gets the people involved.

When I first proposed this design to Dan (Bombshell, who's helping me develop, write, and troubleshoot, he saw this as a 3-mana card too. I'm reluctant to go there simply because Serix has the ability to produce so many tokens so quickly. That's really his purpose. It's a narrow one, but a brutally efficient one.

Maybe citizens get haste too...

This is one of those cards that I'm torn on. Fletcher is right that, as a civilian, Serix should not have the p/t reflected in a warrior or monster.

But making it work is difficult. Casting this on turn 4 is rarely what you want to do and the randomness of the citizen generation means that you may get 4 or more--but you may whiff and get nothing. That said, there is a possibility of recovery after Wrath, or even replacing itself after hit by Doom Blade and bouncing this creature is all but terrifying.

Because Serix has haste it's really better to see him like a scalable Ambassador Oak. I still think it's more attractive at 3 mana but what wouldn't be?

I'm willing to follow Sean's lead here because without actually playing this card I can't say that it wouldn't be a blowout every time it hits.

Fair enough.

Would it make sense then to give his ability an activation cost? Maybe make the creature cost , and give him an activation cost of , ? That way, the haste is stil relevant, and the creature is still a small creature with square stats, but the constant paying of mana makes him fair... at least in my mind...

That's actually a really interesting option...

Oh yes, very good call indeed. This is much better now.

Yeah, I like this version.
