That's still a bit above his budget, for 20$ a pop or so per Haruka, not to mention the minis needed to catch Healing Wave and Chain Heal. Thangal itself is about 12$ or so too. All told, starting from scratch and assuming he needs some extra commons to get cards, I'm seeing this as a 70$ or so warband...
Ironically, I think that's one of the cheapest tier 1 warbands. Though this compares really well with other games (Tier 1 Magic decks are in the 300-400$ range).
