I'm a bit unclear on responding to card placements.

Suppose I set one card face-down - does my opponent have a chance to respond to that (e.g. does he have priority?)?

Suppose I draw a card in my draw phase - who has priority at this point?


These questions are probably trivial, but they've been bothering me for a while.

The opponent is always allowed to respond to the turn player's actions.

This can be anything from drawing a card in your draw phase, to moving on to another phase, or even setting a card on the field (spell or trap).

In your scenario, the opponent would be able to place an effect on the chain because the turn player has just drawn a card.

let's look at this from outside the box...

in the Draw Phase, Standby Phase, Battle Phase, and End Phase, in a way, it really doesn't matter who has Priority, since you can always chain to the effect of the opponent's card effect with only a Speed 2 or higher effect. and afterwards, before the Phase has ended, you can always start a new chain by either player before moving to the next Phase.

Priority actually comes into play moreso in MP1 and MP2. where Speed 1 cards and effects can only be played.

i'm not sure where an instance would be where it may make a difference in the other Phases who actually goes first. heck, in most instances a player would want to actually go second if one player plays a direct damage card that would finish the game, and the other chains with their own card. then, the second player's effect would resolve first, and they would actually win the game.

i believe this is the reason why the rulings usually state "... can only be activated when the last thing to resolve on the field is <this>..."

then, the resolution of the last effect in the previous chain sets up a condition for activating other cards in the next chain somewhere.

but maybe there's other reasons... i'm sure someone will point that out... :)
