Can you attack a tapped creature in magic the gathering with an attack target creature card?

Answer 1

Creatures cannot be 'attacked' in Magic the Gathering. Players are attacked, and creatures are declared as blockers, although there are a few special abilities that can force things to attack or block.

A tapped Planeswalker can be attacked, as per the usual rules for declaring attacks against Planewalker cards.

Targeting a creature with a damage dealing spell or ability is not 'attacking' them. The creature being tapped has nothing to do with its targeting eligibility, it can still be targeted by cards that deal damage.

Damage spells never target Planewalkers directly, the cards target the controlling player and the damage redirected to the Planeswalker from there. This can be done to a tapped Planeswalker.

Answer 2

The question as is doesn't make sense because in Magic, you do not declare attacks against creatures. The turn player declares attackers, and the defending player declares blockers.

- A tapped creature can't be declared as a blocker.

- Nothing special happens if a creature declared as a blocker, becomes tapped. Damage is dealt as normal.

- The 'provoke' ability can force a creature to block a certain attacker. Provoke specifically untaps a tapped target so it can block.

- A creature that is tapped can be targeted for spells and abilities as normal, ie, a creature is not suddenly immune to having Shock used on it, just because it is tapped.

Answer 3

Being tapped or not doesn't affect any spell or ability except for one that specifically says the target must be untapped.

Cards that can deal the equivalent of a round of battle damage to other creatures, can do this to a tapped creature. Even though it's 'as if' they battled, they are not actually attacking or blocking by the definition of those mechanics.
