1mana monsters

1 mana monsters already have the best stats per mana cost without the abilities. plus there are much fewer "all enemy monsters take x damage" abilities compared to "target monster/entity is destroyed/obliterated" (usually at a high premium too, like VOIP!), so your total attack power is somewhat protected further.
people didn't use them before, well at least i didn't, i dunno about others, but it's because its cheap and boring.
abilities that make 1mana monsters stronger only makes them cheaper (soldier synergy on K-guy for example).
the intention i'm sure was to get people to incorparate 1mana monsters into their decks, by giving them abilities that would go well with bigger monsters. unfortunately i don't think any (besides maybe lowly slime) really accomplish that.

so really i have to wonder if they are honestly balanced better now. (mubble's dizzying and fairy's sac bonus aren't too bad though. its really just the ones that boost attack of 1mana monsters. and as i said earlier k army guy is the worst culprit. most soldier types are 1 or 2 mana afterall)
