But yeah he's correct. Or belle is I should say. All you need is 25%(devs algorithm cause them to round up so 24.6 does it for me) of your lands to have spy buildings. This does not include towers. Meaning, 49 lands, you have 19 towers. Leaving 30 lands with action based builds. 10 of those must be spy build to get hansel hitting mechs.
@iprophet. In your example: 30/4 = 7.5 lands = 25%. Hybrids being between 25% and 75%, makes it 8 lands to get hybrid mechanics.
Hansel killer it could be a hlbc with about 10 Hatcher lv3 on hl and a lv3 castle all SOS lv3 on low lands and 13volary on hl and 2 tower at lv3 And a pure spy ally a
