Some really good draws there.
Sherry (right next to prince) is a godsend for mostly F2P accounts since when you get around to AW her she buffs all gold and silver units (and bronze and iron if you ever use those; bronze are useful for certain maps I'll admit) and she's a solid duelist herself
Rachel (right under prince) is a Pirate and probably the 2nd best one (after the OP black Minerva). Pirates, compared to archers, trade attack speed for huge range and attack advantages (and a powerful but VERY short duration slow). Rachel is an excellent ranged alternative to Bashira and will help you get Spica via the Trading Post (which requires the Demon Crystals obtained from Thursday's Crystal Keeper daily which demands a lot of ranged damage)
Zenobia (next to Rachel) is the 2nd best soldier we have (same skill as Jerome, the best one, AW ability makes her better fighter but worse for UP generation which is soldier's primary role, with secondary role being early blocker), definitely a keeper.
Mia (level 34, next to Lolonee and under Belinda) is a Feng Shui User, a multi-target healer who reduces terrain effects like poison and initial HP loss (great on the desert maps and dailies). Don't let her low attack stat fool you, she heals 2 at once (3 after AW) so if you place her right her Attack is basically doubled. Also a keeper.
Bernice (below Mia) is the best tank amongst the gold and silvers, level her and she'll be your main tank for a long time. As a typical Heavy Armor, her offense sucks so you'll need to back her up with ranged damage support.
Kerry (below Rachel) is a good UP ramp as a Valkyrie, if she deals the killing blow you get 1 UP and she gives back most of her cost if you withdraw her (all if she's AW). With skill she can one-shot a lot of weaker mobs.
Yuyu (left of Katie) is a witch who totally outclasses Cloris (Cloris wins attack during skill but Yuyu has better damage outside skill and can extend range with skill). Ditch Cloris mostly, level Yuyu for your witchly needs.
