Added ability DOESNOTUNTAP , see _cards.dat from 10E (Colossus of sardia, dehydratation). Test suite OK. The ability does not work with enchant creature (as for protection from...) So Dehydratation is hardcoded (can be aliased if necessary) Small bug with dehydratation, will untap creature when cast... WHY ? Any Idea/Solution welcome...
