I must compliment SP on the new Teamshop Update. There are some excellent choices, except to those people who still think Thetys is the best monster ever (she maybe was 2 years ago, well no, not even then), or to self entitled spoiled elites who can only think of ranking the next Nemesis.
Shannara's Bodyguard: possibly the most overlooked, recent monster. He has the life of a Nemesis, hits very hard on metal (Talos), is immune to stun, can remove debuffs, has some stun denial himself and even can taunt if that s what you need. Oh, and a killer special. 950 coins is an insult to his class.
Ingvar's Bodyguard: Certainly not the best Bodyguard, but still a very decent Light choice. 1100 coins seems a bit overpriced compared to Shannara's BG.
Toy Master: This was one of Your Master's favourite monsters. A very versatile denier/disruptor from the badly covered Family Book. A pity about his useless trait, but certainly worth getting if you are lacking in this book. 1250 coins seems a fair price.
Ralbog: A half decent monster for Underworld and Evil Legions. Unfortunately he simply does not hit hard enough for modern standards, but he is difficult to ignore in battle when he can burn/bleed and shield himself. Same price as Toy Master.
Cyan Nathura: A nice monster from Superheroes. Heals, poisons, regenerates. If set up properly she can be really troublesome. A pity that with 1500 coins she seems a bit over priced (because of her gold production? Imo that really should not be a factor in determining the price)
