To replace Nefarious Researcher. UB is no longer research

This is for sure, not .

I don't know whether UB weaklings wants a mill subtheme. Thoughts?

Well, mill is tough because it requires you to bury deep into it. If we are using this uncommon to support the low-power archetype, then it should have a more universally useful effect.

How do feel about "that player looses 1 life and you gain 1 life."? It's not a powerful effect but if you can hit with 2 thopters the turn you play this I think it will feel like a good turn.

Fair enough. I was kinda hoping to make it feel a bit more blue than that.

I was considering draw a card lose 1 life.

Look at the top card of that player's library. You may put it into its owner's graveyard?

fateseal is generally considered too unfun, especially if you might be doing it 2 or three times every turn until your opponent can draw something to stop you. We could Dakra Mystic but that still feels a bit more complicated than I would want.
I'm not against paying life for cards. It think your vision of this deck is better at blocking than what I was thinking.

Edit - just read the latest edit. I like it.

I like this. Could it be when they attack, or is that too unfun?

Also, apparently Skulk didn't perform very well in SoI, so isn't likely to be evergreened.

Change looks good. I love this guy.

Had three of these in a recent playtest, they are really really good and might need to be changed to a 2/4 or 5cmc

However they are very fun to play
