Mostly the same answer as this, except for two points:

• Obviously, you check affect_me(instance->damage_target_player, instance->damage_target_card) instead of affect_me(player, card).
• The combat AI's handling of KEYWORD_REGENERATION is pretty broken, since it always assumes the activation cost to regenerate is exactly one mana of the regenerating card's color - put this on a Serra Angel, for example, and it assumes it can regenerate iff the angel's controller has open. (And always exactly , even if the real mana cost wasn't 1 mana, or if there were other activation costs - the AI still thinks Blessing of Leeches and Molting Snakeskin and Soul Channeling all read " : Regenerate enchanted creature" for white creatures up until the point where it actually tries to activate them.) I don't remember how it deals with multicolor creatures offhand.
  
  If you're adding KEYWORD_REGENERATION only during EVENT_CHECK_ABILITIES, and not EVENT_ABILITIES, this can partially be worked around by checking the activation cost at that point, but the AI will still ignore it if it doesn't have or whatever color available.

edit: fix mana symbol markup

That is what I always thought according to my tests,thanks for this confirmation.
