1mana monsters

To those who think that Skyrian's 'portable gauntlet' is exactly the same as a dizzier, note that:
1) If he hasn't activated his ability yet, the attackers just attack directly (or attack other monsters) and ignore him, unless he's dizzy, in which case they slaughter him, of course, just like the dizzier.
2) If he has activated his ability, the attackers designate an expendable flanker at him instead of the beefiest attacker.  Generally, that's all a dizzier will dizzy anyway, but they at least have the option to dizzy the beefy attacker if they are willing to sacrifice themselves in the process.
3) Most dizziers can counter at least some subset of activated abilities-- all of them can at least counter E-speed abilities on their own turn.

Combine that with vulnerability to basically any sniper and Foombolt, and I don't think is too inexpensive.  After all, Sparks' stats aren't tremendously underpowered for her cost (maybe ~85%), with a similar (probably better) ability, and 12/12 is probably comparable for 1.

As for citizen, well, we could give it some other support role befitting its noncombatant resident of Kel'Sor status, like " Undizzy target dark elf", except that would break when combined with Faritin and a Manamancer.  How about a Slime Leader-ish ability, like " Target Dark Elf gains 10 life until end of turn"?

For Gremlin, frankly, A-speed dizzying of devices seems fine to me.  He still only affects a tiny percentage of cards in the universe, given that many of them aren't affected by dizzying at all, several are useless, and two are donations.
