how often, in your opinion, is this built in games on CMCs, 8mm, or fixes? (Angels)

More often than Green or Red Dragons.
Rarely on day 4 can you confidently say that by 115-117 you'll have 25,000 gold (not counting the 4,000 already spent) — and you already need to decide between Cavaliers or Angels.

Castle
Angels in Fort (29,000)
Cavaliers in Castle (18,500)

Barbarian
Bears with Castle (23,000) and there are free days, and overall it's not problematic in terms of construction. (gold/crystals)

Swamp
1-6 with Castle (18,500)
1-7 in Citadel (22,500)
1-7 with Castle (27,500).
(gold/ore = no problems)

Rampart
1-6 in Castle (19,000) with Elf upgrade
1-7 in Fort (23,000) — but then without Elf upgrade and generally no spare days! And the biggest downside is that 1-7 in Fort is worse than 1-6 in Castle (too bad 1-7 in Citadel is impossible :smile32: )

Dungeon
1-6 in Castle is meatier (and only 22,000).
Even worse with Red Dragons: 1-7 only in Fort, without Troglodyte upgrade and with Harpies built (28,500)

Conflux
1-7 in Fort (20,500 + 1,500 if no Air Elementals)
1-7 in Citadel (23,000)
1-6 in Castle (18,000)

Tower
1-6 (without 5) with Castle (19,000) sometimes in Citadel (14,000) :)
1-7 in Fort (18,500) — but is it needed? Titans rule :smile26: on 121, 2 Giants, 4 Nagas, and 150 Marksmen will only scare away Goblins

Inferno
1-6 with Castle (without 3) 19,500
1-7 in Fort or Citadel up to 27,000

Necropolis
here it's almost not critical
1-6 in Castle (23,000)
1-5 in Citadel (without 3) (9,500) :smile04:

Only Shakti develops cheaper
1-3 in Citadel + Troglodyte upgrade + Mushrooms + Portal (8,500)
