Shandalar - Program Bugs

My guess it has something to do with Flash. I know Korath mentioned he had to do some work-around stuff to get the ability to work and I've heard it caused a few problems like this.

It's not triggering. What's happening is that the card-drawn trigger is set to allow response, which lets you interleave instants and instant-speed activations among the triggering cards. You only see it when there's a Horizon Chimera or similar card in a player's hand because normally this trigger isn't dispatched at all for performance reasons; and it's being highlit because you're able to cast it normally.

Interleaving instants with normal triggers like this doesn't work very well at all, which is why it's not normally done. It doesn't even amount to a poor man's version of putting triggers on the stack.

The original game does it for TRIGGER_PAY_TO_ATTACK (listened for by Leviathan, Brainwash, and Jade Statue), TRIGGER_PAY_TO_BLOCK (Jade Statue), TRIGGER_DRAW_PHASE (Nafs Asp effect), and TRIGGER_REPLACE_DRAW (Ring of Ma'ruf, Aladdin's Lamp), presumeably so you can cast Dark Ritual or Sacrifice to pay their mana costs. It's also set, less explicably, for TRIGGER_END_DRAW, TRIGGER_END_MAIN, TRIGGER_DISCARD (all just Basalt Monolith). I expect I set it for XTRIGGER_CARD_DRAWN because all the other triggers and replacement effects in draw_a_card() have it.

It's not actually needed to play Dark Ritual and similar for those costs, though, since the game lets you cast them at the 5th-edition-era Mana Source speed. So I'm going to forcibly disable it by ignoring that argument.
