Bounty hunt says:

Ongoing: Whenever a character an opponent controls leaves play, put a bounty counter on Bounty Hunt.

Remove two bounty counters from Bounty Hunt >>> Draw two cards. Use only if you control a Wild Pack character.

"leaves play"

what does this mean?

Does it mean that whenever a character is ko'ed, removed, or returned back to an opponent's hand, i am able to put a bounty counter on bounty hunt? If so, perhaps an opponent has 3 characters, ignoring all plot twists, that would mean that the opponent could only choose 1 character to recover and send two to the ko'ed pile. By definition of leaving play, would that mean i would get 2 bounty counters?

Leaves play means:
go from "in play" to somewhere that is not "in play".
In practice this means from the field to the hand, KO'd pile, remove from play, or even the deck.

So yes, the situation you describe is correct, though the counters would come on in the draw phase of the next turn.

what do you mean by "even the deck" and why would the counters only come on in the draw phase and not during the time a character "leaves play"?

If the character is moved out of the "in play" zone then it is considered to have left play. The destinations for that character to go are the your opponents KO pile, your KO pile, the opponents hand, your hand, your opponents deck or your deck or to the Removed From Play zone.

During your situation, 3 stunned characters, 2 are going to the graveyard, each Bounty Hunt plot twist would recieve 1 counter for each character leaving play. Therefore, Bounty Hunt would recieve 2 counters. They are put on Bounty Hunt after the effect resolves, no matter when that is.

I include "your KO pile, graveyard or hand" because your opponent may control characters that you own. For example, if Ultra Humanite takes your 5 drop and then your 5 drop gets KOd somehow, Bounty Hunt would still recieve a counter for it because at the time, your opponent controled it even though you own it.

He said "even the deck" because it's relatively rare for a card to go directly from play to a deck---some cards like Roy Harper <> Speedy can do it, but it's not common. At least, I'm assuming that's what he meant; correct me if you were implying something different, Jason.

And you wouldn't get any counters until the next turn's draw phase because there is no priority during the recovery phase's wrap-up, when the game KOs your stunned characters. Any effects which are triggered during that period must wait to go on the chain until the next point of priority, which is during the draw phase.

For a more succinct summary of triggers, though, here you go: any time a character goes from a front or support row to anywhere other than a front or support row, it has left play.

ok, correct me if i'm wrong...

scenario...

i have bounty hunt and i stunned 3 of my opponents characters.

RECOVERY PHASE

he recovers 1 character and puts 2 characters in his ko'ed pile

i recover however many

DRAW PHASE

i draw two cards, then i put two counters on bounty hunt, in which i draw two more cards after the intial two.

he draws two cards.

Close.

As the draw phase begins, the game-based draw effect is placed on the chain. After that effect is on the chain, the waiting triggered effects will be placed on, too. This means you'll get your Bounty counters before you draw your two cards for the turn; if you wanted, you could draw two cards from Bounty Hunt before the game-based draw occurred. Since you and your opponent will draw those two cards for the turn at the same time, there might be an occasion where you really want to draw cards before the opponent can.

if, perhaps, i ko my opponent's character during the combat phase, would i be able to play a bounty counter on bounty hunt, and if there was a bounty counter there already, would i be able to draw two cards then?

Yes, that'd be fine.

Here's the thing---powers are pretty much never triggered when a player has priority, since they're always triggered off of things happening. We don't want triggered effects being placed on the chain in the middle of resolutions or payments, since the timing would become very confusing, very quickly.

The solution:Triggered effects wait around, to be placed on the chain just before the next time that a player would get priority.

For powers that are triggered during resolution of effects, this is easy; you add your triggered effect to the chain right after the resolution finishes. If Finishing Move triggers Bounty Hunt, you'll get the counter soon after. But for powers triggered during the wrap-up, the next point of priority happens to be in the draw phase, so that's when you'll add your triggered effects to the chain.

Is that statement correct? If I use Bron Char to put your 2 drop into your resource row, it hasn't left play, has it?

By becoming a resource, the character card changes rows, and the character object ceases to exist upon hitting the resource row, so it ought to trigger any 'leaves play' effects.

A chararacter that is moved into a resource row does 'leave play', and will trigger Bounty Hunt.
