You can turn in the new cards if defeating the player gives you five cards or more.
For example, if you have one card, and you kill someone that has four, that means you have five cards and you can turn them in mid-turn.
But if you had one card and killed a player that had two, that would leave you with three cards total, and you won't be able to turn them in mid-turn.
This was supposed to be explained in the Tutorial, but I don't see anything written about it in there. Hopefully 4myGod can add it.
