I'm trying a Banana Paladin deck for low ranks (more like rank 15, not 5-10) and it's a lot of fun.
I got 2 Murloc Knights and 2 Mukla's Champions in it; the perfect situation for me is having board control early, play a Sludge Belcher at turn 5 (maybe another one with coin at 4 - or a defender of Argus on 4), Murloc Knight + hero ability (4+2 mana) at turn 6 and mukla's champ + hero ability (5+2) at turn 7.
You want board control and some taunt because people will go for those Murloc Knights and Mukla's Champs; getting hit by Flamestrike at Turn 7 (or similar stuff - or hex, polymorph, fireball...) is no fun either.
My deck is just for the sake of fun at low ranks and pretty low budget; I got 8 rares (2 sludge belcher / 2 Knife Juggler / 2 Muster for Battle / 1 Aldor Peacekeeper / 1 Defender of Argus) and no epics or legendaries in it. The average mana cost of my cards is 3.
By the way: I'm glad when people snipe / silence my Murloc Knight and not Mukla's Champion, because I got a full board easily (have to sacrifice 1-2 weak units per round quite often if I got murlok + mukla on the board) and mukla's ability (giving up to 6 minions +1/+1) helps me much more than having one additional random murloc.
Many people at low ranks ragequit when I summon a Murloc Knight with my Murloc Knight - or when I play my second Murloc knight if they manage to clear the board with flamestrike or similar spells

edit: I can't stress out 2 points enough: my deck is for low ranks and for fun, not for competitive play at high ranks.
