Hi, im 
Summoner:
Lyanna Natura is a very versatile summoner that can be rented at reasenable low prices, it gives all you monster 1+ health point wich is always useful(for example summoners that gives you shield could be countered by a water magic tem since magic damage ignores shield points).
Tank:
!
Flesh Golem is arguably one of the best commom tankers in the game especially at lvl 3 card and above due to heal ability, he has high health points, decent speed for a tank and 2 attack point, and when paired with a healer in the back line, for only a 6 mana cost it can survive for a long time.
!
Ranged Attackers
Earth Elemental has high health points and ranged points, notice that this a rare card and can be used at maximum at lvl 4 in silver elo for example, but this card at lvl 4 has 2 ranged attack points and a heal abilitty wich makes him a damage dealer and a tank, very versatile with only 3 mana cost.
!
Barking Spider is a similar card to Earth Elemental, but as commom card can be used at lvl 5 in silver elo, but at lvl 6 it gains Blind ability wich increase the chance of dodging an attack, in some cases a dodged attack could be the difference between winning and losing.
Javelin Thrower is another card similar to Earth Elemental and Barking Spider, but at lvl 4 has 3 ranged attack damage and. This card has Piercing ability from lvl 1 wich makes your attack hits the enemy shield and the health of the oponent(for example if you have 3 attack damage and the enemy has 1 shield points, her attack will hit the shield and the the remainder damage will attack life points of the enemy), this ability makes you potencialy kill enemies with high shield points 1 or 2 rounds earlier.
Supports
Failed Summoner is such a underrated card, for example in Gold elo as a commom card it could be used up to lvl 8, this card at lvl 8 have 9 health points and both Magic Reflect and Remoralize abilities while costing one 2 MANA POINTS! In low mana rounds it can be used as a tank to absord damage giving your damage cards time to attack.
Khmer Princess is one of the 2 healers options in this setup, at lvl 4 this card has Tank Heal ability which make Flesh Golem survive a lot more, keep in mind that this card costs only 2 mana points making extremely flexible to be used in many rounds with low mana cap.
Wood Nymph is a strong healer than Khmer Princess especially at Gold elo because at lvl 6 it has Strenghten ability that gives all you monsters a 1+ health point(basically the same that Lyanna Natura summoner), besides having more health points. But the downside is that it costs 4 mana points and is often not as much versatile to be used in low mana cap rounds as much as Khmer Princess
