1mana monsters

Lowly Slime: Gives a reason to not just use Slime Champion, accept
Kelar Citizen: The mana gen seems too low to be worth while given it only works with an expensive card, but the flip side is that this combos well with Manamancer on top of that... accept
Gremlin: Good to see lifebar hate back, accept (the only way this really posses a threat is if your deck relies on lifebar monsters).
Skeleton: Accept
Melrak Follower: A more vulnerable form of Smash Hopes (can be countered AND killed) with a lower speed. I guess sense it can damage directly before killing an effect, just make it at least C speed and then I'll accept.
Holy Acolyte: Accept
Fairy: As long as it doesn't affect the tokens, accept.
Mubble: Make it E speed so that basically it's nothing more than a beatstick guard. Even if you keep it at D speed however, accept.
K-Army Guy: Thematically speaking all the Heros should take minor damage (random encounters wear down your H.P., and the EXP gained from that increases attack). Unfortunately doing that hoses Sheena, especially in her NPC mode. Accept just on idea.
Skyrian Soldier: Accept.
Lokar Guard: Accept
