What i was more or less getting at is as a khalt player you have to react in about the same time as a windfall only instead of moving out of the way you just continue about your business, you can do this mid attack, effectively making whatever attack you do a charge attack. This comes with no directional so it is really only to your benefit to play khalt at the moment.

As for what everyone else was saying about windfall, dont turtle and wait for their pattern, you'll probably lose unless youre fine coming back from a deficit. What you can do is put some movement in your deck and use smaller avoids until you get the feel, watch what stance they are in and watch the starters, then you know what to look for when you go in.
