Gideon Jura

15/06/10

Gideon Jura’s first ability doesn’t lock in what it applies to. That’s because the effect states a true thing about a set of creatures, but doesn’t actually change the characteristics of those creatures. As a result, whatever creatures the targeted opponent controls during the declare attackers step of their next turn must attack Gideon Jura if able. This includes creatures that come under that player’s control after the ability has resolved and creatures that have lost all abilities.

Gideon Jura’s third ability causes him to become a creature with the creature types Human Soldier. He remains a planeswalker with the planeswalker type Gideon. (He also retains any other card types or subtypes he may have had.) Each subtype is correlated to the proper card type: Gideon is just a planeswalker type (not a creature type), and Human and Soldier are just creature types (not planeswalker types).

If a creature controlled by the affected player can’t attack Gideon Jura (because he’s no longer on the battlefield, for example), that player may have it attack you, another one of your planeswalkers, or nothing at all.

If Gideon Jura becomes a creature due to his third ability, that doesn’t count as having a creature enter the battlefield. Gideon Jura was already on the battlefield; he only changed his types. Abilities that trigger whenever a creature enters the battlefield won’t trigger.

Say you activate Gideon Jura’s third ability, then an opponent gains control of him before combat. You may have any of your creatures attack Gideon Jura (since he’s still a planeswalker). Then Gideon Jura may block (since he’s a creature). He may block any eligible attacking creature, including one that’s attacking him! During combat, he behaves as an attacked planeswalker and/or a blocking creature, as appropriate. For example, he deals combat damage to any creatures he’s blocking, but he doesn’t deal combat damage to any unblocked creatures that are attacking him.
