1mana monsters

Alright, into play abilities (proposals):
Fairy: Do we need to change this to gain when comes into play or is just one "if not a token" conditioned card fine?
Gremlin: Into play, opponent takes 5 damage.
K-Army Guy: Into play, all opponent's monsters lose 2 attack.
Mubble: Already has an agreed on ability, I'd suggest just nerfing the ones produced by Mubble Woods.
